美国无人机在伊拉克击毙曾杀害海军陆战队员的伊斯兰国武装分子

The U.S. military said Sunday one of its drones in Iraq has killed an Islamic State fighter it believes was responsible for a missile attack last month that killed a U.S. Marine.

A spokesman for the U.S.-led operations against the militants, Colonel Steve Warren, said the drone attack killed Jasim Khadijah, described as a former Iraqi officer and "a rocket expert," and five other Islamic State fighters.

Warren said Khadijah had controlled the Islamic State rocket attack that killed Staff Sergeant Louis Cardin and wounded eight other Marines at an artillery position in the Makhmur area of northern Iraq.

Cardin was the second U.S. combat death since the start of a U.S. campaign to fight Islamic State in Iraq in 2014.
