I’d be surprised if the gunmen weren’t from Ansar al-Sharia.

TRIPOLI, Libya (AP) — Unknown assailants shot an American teacher to death as he was jogging on Thursday in Benghazi, a hospital official said, underlining persistently tenuous security in the eastern Libyan city where the U.S. ambassador was killed last year.

Fadyah al-Burghathi, spokeswoman for the Al-Galaa hospital, said the body of a man from Texas was brought to the hospital on Thursday with gunshot wounds. A security official said the American taught chemistry at the city’s International School, a Libyan-owned institute that follows an American curriculum.

No one has claimed responsibility for the teacher’s killing but suspicion is likely to fall on Islamic militants active in the city.

The security official, Ibrahim al-Sharaa, said the American was jogging near the U.S. Consulate, where the U.S. ambassador and three other Americans were killed by Islamic militants in September 2012.
