A federal jury found a second Libyan militant guilty on two counts for their role in the 2012 attack on the U.S. diplomatic mission and nearby CIA post in Benghazi, Libya that killed four Americans, including the U.S. ambassador to Libya; the jury was deadlocked on 15 other counts.

A Washington jury found Mustafa al-Imam, 47, guilty on one count of conspiracy to provide material support to terrorists and one count of destroying government property.

The partial verdict did not include decisions for other charges such as murder and attempted murder. U.S. District Judge Christopher R. “Casey” Cooper told jurors to continue deliberating the charges, which include accountability for the murders of Ambassador J. Christopher Stevens, State Department communications aide Sean Smith and CIA security contractors Glen Doherty and Tyrone Woods.
