WASHINGTON — Special Operations troops killed a senior Islamic State leader in a helicopter raid in a remote area of Somalia on Thursday, a U.S. official said. A U.S. official identified the man as Bilal al-Sudani, an Islamic State leader operating in Somalia.

United States Africa Command said in a news release that the U.S. military had “conducted a successful counterterrorism operation in Somalia.” The White House is expected to make an announcement later on Thursday.

Africa Command said in its statement that no civilians were injured or killed. The U.S. official also said that no U.S. troops were injured or killed.
