The Defense officials and Pentagon leaders on Monday wouldn’t detail the intelligence recovered on Saturday, but said it consisted of data-storage devices and other files that will add to the understanding of Islamic State as the U.S. and allies continue pursuing its leaders and operatives.

In a sign of the continuing nature of the operations, a senior State Department official on Monday said a second U.S. raid closely following the operation against Baghdadi resulted in the death of Islamic State’s top spokesman.

The senior State Department official described the spokesman, Abu al-Hassan al-Muhajir, as “kind of No. 2” in Islamic State. The operation was first announced by the Kurdish-led Syrian Democratic Forces, which worked with U.S. troops in fighting Islamic State before President Trump ordered a U.S. withdrawal.
