Three separate attacks, including an assault on the military base of Monguno, killed dozens of people in Nigeria’s northeastern Borno state. Boko Haram, which has allied itself with the Islamic State West Africa Province (ISWAP), claimed responsibility for the attacks. The other two targets were a United Nations office and a refugee camp which hosts an estimated 150,000 displaced civilians

The attack on Monguno was supported by heavy weapons and rocket launchers. At least 15 people, including a four-year-old girl, and nine soldiers died; many more were wounded. The U.N. confirmed in a statement that the “non-state armed group operatives” entered Monguno in the late morning. The Nigerian military said that its forces had “successfully repelled” the attack and killed 20 jihadists.

“They fired rocket-propelled grenades indiscriminately which fell on homes, killing three people and injuring many others,” a civilian told French news agency AFP. “I saw the bodies of the two soldiers and the militia member on the streets after the fighting.”

Civilians from the Goni Usmanti village in Nganzai told AFP that the jihadists shot and killed 38 people and set a truck on fire with passengers inside. The BBC reported that hundreds of civilians were injured in Nganzai during the attack and the local hospital was overwhelmed, forcing some of the injured to lie outside awaiting help.

Security officials said that at least 20 soldiers and 40 civilians were killed in the first two attacks. The third attack was perpetrated on Zuwo village in the Gubio area but the number of casualties there has not yet been confirmed because of poor telecommunication services in the area.

Idris Yahaya, a member of the local community security force told the AP the attackers burned down several houses in the village and that they have recovered “about 40 corpses in and around Usmanti village.” 

The jihadists appeared to have come from the neighboring countries of Chad and Niger. The area around Lake Chad is where Boko Haram is most active and from where all three attacks sprang

On June 9, in an earlier attack by ISWAP jihadists, 81 people were killed in Gubio.
