An Iraqi militant who was behind last month's attacks that killed more than 400 members of the minority Yazidi community has been killed, the US says.
The villages were razed to the ground
Abu Mohammed al-Afri, also known as Abu Jassam, was killed in an air strike on 3 September near the northern city of Mosul, US spokesman Mark Fox said.
He described the man as an associate of the leader of al-Qaeda in Iraq.
Some estimates say more than 500 died in the multiple bomb attacks in two villages in north-west Sinjar region.
Another 400 people were injured by the blasts - among the deadliest in Iraq since the US-led invasion in 2003.
No more threat
Abu Mohammed al-Afri - who was responsible for "the planning and conducting of the horrific attack" against the Yazidis on 14 August - was killed in a coalition air strike 115km (70 miles) south-west of the northern city of Mosul, Rear Admiral Mark Fox told reporters.

Adm Fox described him as an associate of Abu Ayyub al-Masri, the leader of al-Qaeda in Iraq.
"Abu Jassam is no longer a threat to the Iraqi people," he said.
The co-ordinated bombings in the villages of Qataniya and Adnaniya - involving a fuel tanker and cars - ripped apart houses, many of which were made of no more than clay and mud.
Yazidis worship an archangel, sometimes represented by a peacock figure, believed by some Christians and Muslims to be the devil.
Tensions between the Yazidi sect and local Muslims have grown since a Yazidi girl was reportedly stoned by her community in April for converting to Islam.
