"Abu Ibrahim al-Hashimi al-Qurayshi, 45, blew himself up with his family, including four women and six children, rather than surrender to troops who landed by helicopter..."

"... and surrounded the house where he had been hiding, the president said.... [W]hen special forces commandos descended from Black Hawk helicopters guarded by Apache strike helicopters, things did not go entirely to plan, according to witnesses and Washington officials.... 'We heard the translator asking, via speakers, [for] the residents of the house to surrender and the women and children to leave before the attack started. The operation obviously didn’t go smoothly because it lasted for two hours and ended with bombing the house,' [a town resident] said.

"Pentagon officials said earlier that the mission had been met with resistance and that the 'bombing' was the Isis leader, an Iraqi, blowing himself up with such force that half the third, top, floor of the house was destroyed.... Witnesses said that some of the bodies were flung clear of the wreckage, landing in the garden, including those of two children.... Qurayshi, whose real name was Amir Mohammed Abdul Rahman al-Mawli al-Salbi, was an officer in Saddam Hussein’s army before joining al-Qaeda after the American invasion of 2003. A trained theologian, he became Isis’s chief ideologue....  Biden said that Qurayshi had been the driving force behind the genocide of the Yazidi people. 'We all remember the gut-wrenching stories of mass slaughter that wiped out entire villages, thousands of women and young girls sold into slavery [and] rape used as a weapon of war,' the president said."
