Prominent French militant Jean-Michel Clain was killed last month, his wife told AFP Tuesday after fleeing the last redoubt of ISIS in eastern Syria. Clains wife Dorothee Maquere said he was killed in mortar shelling after being wounded in the coalition drone strike that killed his brother Fabien, who was Frances most wanted extremist. "The drone killed my brother-in-law and then the mortar killed my husband," she said at a screening area run by the Kurdish-led Syrian Democratic Forces, which is spearheading the battle against the last pocket of ISIS territory. Maquere and her children were among the last civilians to leave Baghouz, the farming village on the banks of the Euphrates where diehard extremists are making a bloody last stand. Fabien Clain, 41, gained notoriety after voicing an audio recording claiming responsibility for the November 2015 attacks in Paris, when ISIS militants slaughtered 129 people in coordinated attacks. The US-led anti-IS military coalition, of which France is also a member, confirmed Fabien Clains death last month. His younger brother Jean-Michel, 38, was wounded in the same February 20 coalition strike on Baghouz, Maquere said, adding that he died in a mortar attack later. While Fabien was seen as a senior propagandist among the foreign ranks of ISIS militants, his younger brother was mostly known as a singer of the "nasheed" chants heard on some of the videos released by the terrorist organization.
