The mistrial in the case of Mustafa al-Imam was declared Monday in Washington after a jury could not reach a decision on 15 counts. The same jury last week found al-Imam guilty of two different counts, including conspiracy to provide material support to terrorists.
Al-Imam is the second militant to stand trial in connection with the attacks that killed four Americans, including Ambassador Chris Stevens.
Ahmed Abu Khattala (hah-TAH'-lah), the head of an Islamist extremist militia who directed the attacks, was convicted in 2017 on terrorism-related charges but acquitted of murder. He was sentenced to 22 years in prison.
