US-Iran Nuclear Talks Face Uncertainty Over Venue as Tensions Rise

The next round of nuclear negotiations between the United States and Iran remains in limbo as conflicting reports emerged Tuesday over whether the talks would be held in Rome or return to Oman.

The uncertainty follows a weekend of high-stakes discussions in Muscat and comes amid growing urgency over Iran’s rapidly advancing nuclear program.

Early reports Monday indicated Rome would host the next round of talks, with confirmations from Italian and Dutch officials, as well as Iran’s Foreign Minister Abbas Araghchi. However, by Tuesday morning, Iran’s state-run IRNA news agency quoted Foreign Ministry spokesperson Esmail Baghaei stating the talks would be held again in Oman.

US officials have not publicly confirmed the location.

Iran and the US held nuclear talks in Muscat, Oman, on April 12. The Iranian delegation, led by Foreign Affairs Minister Abbas Araghchi, presented Iran’s demands and red lines to the US delegation, led by US Special Envoy to the Middle East Steve Witkoff.

The shifting venue comes as President Donald Trump expressed frustration over the pace of the negotiations.

Speaking from the Oval Office, Trump accused Iran of stalling and reiterated his position that Iran must not be allowed to obtain nuclear weapons.

“These are radicalized people, and they cannot have a nuclear weapon,” he said, adding, “I want them to be a rich, great nation.”

The talks follow a previous round of indirect meetings between Araghchi and US envoy Steve Witkoff, mediated by Oman’s Foreign Minister. Despite Iran’s rejection of direct negotiations under current pressure, the two sides reportedly held a face-to-face meeting following the mediated session.

In a separate development, International Atomic Energy Agency (IAEA) Director Rafael Mariano Grossi will travel to Iran this week. His visit aims to restore access for UN inspectors, whose oversight has been curtailed since the US withdrew from the 2015 nuclear agreement.

Grossi is expected to meet President Masoud Pezeshkian and Iranian negotiators upon arrival Wednesday night.

Sanctions relief and uranium enrichment remain the primary points of contention. Since the collapse of the 2015 deal, Iran has enriched uranium up to 60% purity — just short of weapons-grade — and amassed enough material for multiple nuclear weapons, according to international estimates.

Iran insists it will not accept any deal without guarantees, citing past US withdrawals.

“As long as the language of sanctions, pressure, threats, and intimidation continues, direct negotiations will not take place,” said Baghaei.

With time running out and trust in short supply, both sides appear poised for a critical juncture in decades of hostility.

 

Gunmen Kill at Least 40 in Attack on Christian Village in Nigeria’s Plateau State

At least 40 people were killed Sunday night when armed Muslim gunmen, suspected to be Fulani herders, launched a deadly raid on the predominantly Christian Zike community in Nigeria’s north-central Plateau state, according to Nigerian President Bola Tinubu.

Tinubu condemned the attack and ordered a full investigation, instructing security agencies to identify those responsible.

“I have instructed security agencies to thoroughly investigate this crisis and identify those responsible for orchestrating these violent acts,” he said in a statement late Monday.

Witnesses and local sources said the attackers struck without warning, killing men, women, children, and the elderly. Amnesty International confirmed that many victims were unable to escape.

The gunmen also looted and torched homes, according to resident Andy Yakubu, who estimated the death toll could exceed 50.

No arrests have been made.

The attack marks the latest in a string of violent clashes between Fulani herders—mostly Muslim—and Christian farming communities in Nigeria’s Middle Belt, where longstanding disputes over land and water rights have escalated into deadly raids.

Samuel Jugo, a spokesperson for the Irigwe Development Association, said the Irigwe people have lost at least 75 members since December 2024, despite the deployment of more security forces to the region. He called the latest attack “very provocative, vexing and undeserving.”

Amnesty International reported that 1,336 people were killed in Plateau state between December 2023 and February 2024, underscoring the failure of current security measures under Tinubu’s administration.

The violence in Plateau is distinct from Nigeria’s long-running insurgency with Boko Haram in the northeast, though both conflicts continue to destabilize Africa’s most populous nation and threaten broader regional security.

 

Gen. Dan Caine Sworn In as Chairman of the Joint Chiefs After Trump Fires Brown

US Air Force Gen. Dan Caine was sworn in Saturday as the new chairman of the Joint Chiefs of Staff following President Donald Trump’s dismissal of Gen. CQ Brown Jr. nearly two months ago.

Caine assumes the post after Trump signed a waiver overriding statutory requirements, marking the first time an officer has been recalled from retirement to serve in the role.

Caine, a decorated F-16 pilot with over 2,800 flight hours—100 of those in combat—takes over the remainder of Brown’s four-year term, which will run through September 30, 2027. Brown, who had served just 16 months, was fired on February 21 amid a broader shake-up of senior military leadership reportedly linked to opposition to diversity and equity programs.

Due to lacking prior experience as a service chief or combatant commander—requirements under the 1986 Goldwater-Nichols Act—Caine needed a presidential waiver, which Trump signed late Friday after returning from Walter Reed Medical Center.

The Senate confirmed Caine’s nomination early Friday morning in a 60-25 vote, including support from 15 Democrats and Independent Sen. Angus King.

Caine’s path to the chairman’s seat has been unconventional. After commissioning through the ROTC program at the Virginia Military Institute in 1990, he transitioned from active duty to the Air National Guard to pursue fighter pilot opportunities. He flew combat air patrols over Washington, DC, on 9/11 and deployed shortly thereafter to Kuwait.

Throughout his career, Caine alternated between active duty and guard roles, serving in special operations, classified Pentagon programs, and at the CIA. His final position before retirement in 2023 was associate director for military affairs at the Central Intelligence Agency (CIA), where he held three-star rank.

At his recent confirmation hearing, Caine pledged to remain apolitical and committed to lawful conduct. When questioned about how he would respond to illegal orders, including use of military force against civilians, he affirmed his duty to push back.

A formal White House ceremony to mark Caine’s appointment is expected later this week. As of Monday, the Joint Chiefs website had not yet updated his status.

 

Trump Transfers Border Land to Army, Raising Legal Questions Over Migrant Detention Authority

President Donald Trump has directed the transfer of a federal land corridor along the US-Mexico border to the Department of Defense, a move aimed at expanding military authority to detain migrants on American soil.

US officials told the Associated Press that the area will fall under Army control and be treated as part of a military base, allowing troops to apprehend trespassers under military security authority.

The land in question, known as the Roosevelt Reservation, is a 60-foot-wide federal buffer zone stretching from New Mexico to California.

Previously managed by the Department of the Interior, it will now fall under the Defense Department per a presidential memorandum issued Friday night.

The move seeks to bypass the Posse Comitatus Act, which prohibits US military forces from performing civilian law enforcement functions on US territory. By designating the land as part of an Army installation, the administration argues troops can provide base security—thereby detaining unauthorized individuals, including migrants. However, legal experts warn this rationale is likely to face court challenges.

The Pentagon is launching a 45-day test phase in New Mexico near Fort Huachuca, Arizona. During this period, the Army will erect new fencing, post warning signs, and begin detaining unauthorized entrants. Any migrants detained would be handed over to civilian law enforcement.

Currently, about 7,100 active-duty troops and 4,600 National Guard personnel are stationed along the border. It remains unclear if the land transfer will require additional force deployments.

Critics say the administration’s strategy likely violates the Posse Comitatus Act and fails to meet the legal threshold for the “military purpose doctrine,” which allows military involvement in law enforcement only if it is incidental to a broader, legitimate military mission.

The National Security Council declined to comment on the move, which marks the administration’s most aggressive effort yet to involve the US military in border enforcement.

 

First Female Army Ranger Competes in Best Ranger Competition, Finishes 14th

For the first time in the event’s history, a female Army Ranger competed in the annual Best Ranger Competition at Fort Benning, completing the intense three-day challenge and finishing 14th overall with her teammate.

First Lt. Gabrielle White and Capt. Seth Deltenre were among 16 teams to complete the event, out of 52 that began. The remaining 51 teams consisted entirely of male soldiers. The winning team was composed of 1st Lt. Griff Hokanson and 1st Lt. Kevin Moore, both assigned to the 75th Ranger Regiment.

White and Deltenre are based at the Army Center of Excellence at Fort Benning.

The Best Ranger Competition includes over 30 events spanning 60 miles, including land navigation, obstacle courses, weapons qualification, physical fitness tests, and helicopter operations—all executed with minimal rest.

Female soldiers were first allowed into Ranger School in 2015, and since then, 154 women have graduated as of January 2025. White, 25, is a West Point graduate and Black infantry officer assigned to the Maneuver Captains Career Course. She completed Ranger School in April 2022.

Despite the historic nature of White’s participation, the Army has not publicly acknowledged the milestone. Under the current administration, led by President Donald Trump and Defense Secretary Pete Hegseth, the Department of Defense has halted public recognition of diversity and inclusion milestones.

Recent changes to military websites and social media platforms have removed mentions of “firsts” involving women and minority service members.

 

Germany Pledges $142 Million in Humanitarian Aid for Sudan Ahead of International Conference

Germany will provide 125 million euros ($142 million) in humanitarian aid to Sudan, Foreign Minister Annalena Baerbock announced Monday, one day before an international summit in London addressing the crisis in the war-torn country.

The aid will support international and local organizations delivering critical food and medical supplies to Sudan and neighboring regions, Baerbock said in a statement issued by the German Foreign Ministry.

Sudan has been engulfed in civil war since April 2023, when fighting erupted between the Sudanese Armed Forces and the paramilitary Rapid Support Forces (RSF). The conflict has split the country, with the army dominating the north and east, and the RSF controlling much of Darfur and parts of the south.

The war has killed tens of thousands, displaced over 13 million people, and triggered what the International Rescue Committee has described as “the biggest humanitarian crisis ever recorded.”

The international conference on Sudan, co-hosted by Britain, Germany, France, the European Union, and the African Union, is scheduled for Tuesday in London.

According to Germany’s foreign ministry, both warring parties have so far refused to engage in peace talks.

“Death is an ever-present reality in large parts of Sudan,” Baerbock said, labeling the conflict “the greatest humanitarian catastrophe of our time.”

Baerbock cited widespread famine, mass displacement, and systematic sexual violence as defining features of the crisis.

Germany called on Gulf nations to attend and use their influence to help establish humanitarian corridors.

Baerbock stressed that only coordinated international pressure would force the combatants to the negotiating table.

 

Ukraine Parades Captured Chinese Fighters, Warns of Growing Foreign Involvement

Ukrainian authorities presented two captured Chinese nationals at a Kyiv press conference on Monday, alleging they were fighting alongside Russian forces in the eastern Donetsk region.

The men, escorted in handcuffs and flanked by armed Ukrainian soldiers, warned other Chinese citizens against joining the conflict.

The event followed Ukrainian President Volodymyr Zelenskyy’s statement last week accusing Russia of recruiting “several hundred” Chinese fighters for its war effort.

The Kremlin denied the claim, and Beijing responded by cautioning all sides against making “irresponsible remarks.”

The prisoners, identified as 26-year-old Zhang Renbo and 33-year-old Wang Guangjun, said they were recruited through online advertisements and later deployed to the front.

“I hope China can exchange me with Russia and Ukraine and bring me back to China,” Zhang said.

Wang warned others not to join the war and accused Russia of misleading foreign recruits.

“When you really participate in the war, when the moment of the fighting comes, you will find that everything is a lie,” he said.

Two Chinese citizens captured fighting against Ukraine said they were “fed lies” by Russia and that Vladimir Putin’s forces were not as strong as they claimedhttps://t.co/oSimbaln8n

There was no independent verification of the men’s statements or confirmation that they spoke freely.

The incident highlights a potentially expanding international dimension of the war and raises questions about the extent of foreign fighters supporting Russian operations in Ukraine.

 

Ukrainian Drone Barrage Hits Russia’s Kursk Region, Kills Elderly Woman and Injures Nine

Ukrainian forces launched a large-scale drone strike on Russia’s Kursk region overnight, killing an 85-year-old woman, injuring nine others, and setting multiple buildings ablaze, Russian officials said Tuesday.

The Russian Ministry of Defense claimed its air defenses shot down 109 drones over the region, which borders northeastern Ukraine.

The ministry did not specify how many drones Ukraine launched in total.

Kursk regional authorities described the attack as a “massive enemy strike” and shared images of fire-damaged apartment buildings, blown-out windows, and scorched facades. An apartment block caught fire, prompting evacuations, and drone impacts damaged an ambulance garage, destroying 11 vehicles.

Acting Kursk city mayor Sergei Kotlyarov confirmed the civilian fatality and noted that residents of the damaged building were moved to a nearby school for shelter.

The strike follows another Ukrainian drone attack in the region on Monday evening that killed three people, according to Russian officials.

Ukraine has not issued a statement on the strike.

Both sides in the ongoing conflict deny intentionally targeting civilians, although civilian casualties have mounted throughout the war, which began with Russia’s full-scale invasion more than three years ago.

Border regions like Kursk have seen frequent Ukrainian air and ground attacks aimed at disrupting Russian military operations. Ukrainian forces briefly crossed into the Kursk region last year, and while much of that territory has since been retaken by Russia, cross-border operations continue.

South Korea Boosts Semiconductor Support to $23.25 Billion Amid US Tariff Threat, China Competition

South Korea announced Tuesday that it will increase its support package for the semiconductor sector to 33 trillion won ($23.25 billion), up from 26 trillion won previously.

The expanded aid comes amid growing policy uncertainty under the current US administration and rising competition from China, according to a joint government statement.

The country will also expand its financial assistance program for the chip industry to 20 trillion won, compared to the previous 17 trillion. Multiple ministries, including the trade ministry, emphasized the need to help domestic firms manage escalating production costs while staying competitive in the global market.

South Korea is a major player in the global chip supply chain and home to leading memory chip manufacturers Samsung Electronics and SK Hynix. However, both firms lag behind international competitors in areas like chip design and contract manufacturing.

In 2024, South Korea’s semiconductor exports totaled $141.9 billion—21% of the nation’s total exports. Of that, $46.6 billion went to China and $10.7 billion to the United States.

The announcement follows a Sunday statement by US President Donald Trump, who said he would unveil new tariffs on imported semiconductors within the next week. He noted there would be some flexibility for select companies but did not offer specifics.

In response, South Korean Finance Minister Choi Sang-mok said Seoul would engage directly with Washington regarding its Section 232 investigations into semiconductor and biopharmaceutical imports to minimize potential fallout for South Korean firms.

The semiconductor measures come on the heels of emergency support announced last week for South Korea’s auto sector, also facing possible US tariffs. Those measures include financial aid, tax cuts, and subsidies to stimulate domestic demand, alongside diplomatic efforts to mitigate economic impacts and secure new export markets.
