In September, the Pentagon’s senior leadership was briefed by military, intelligence, and law enforcement officials on credible domestic and overseas threats against Washington’s military and civilian leaders, sources reported. These active threats could possibly be related to the assassination of Iranian Major General Qassem Soleimani as Iran may be looking to retaliate.

The briefings, according to media sources, show that security officials believe that senior U.S. leadership involved in the Soleimani assassination has been targeted. NBC News was the first to break the story. 

Iranian MG Qassem Soleimani was killed in an airstrike in January.

This week, Defense Secretary Mark Esper has been traveling in the Middle East and South Asia. His security staff kept a tighter lid than usual on any information regarding his itinerary, suggesting that there are heightened security measures in place. Reporters traveling with Secretary Esper were not allowed to report about his visits to Bahrain or Israel until after he left each country, although he spent two nights in Bahrain.

Officials from the FBI, CIA, and the Pentagon first met on September 22 following an incident involving a senior Department of Defense official who had been followed by an Iranian national after leaving the Pentagon.
