"Abu Qaswarah, also known as Abu Sara, was the Al-Qaeda in Iraq senior leader of northern Iraq," a military statement said.
It said that Abu Qaswarah, a native of Morocco who was killed in a raid in Mosul on October 5, had ties to Al Qaeda in Iraq’s founder Abu Musab al-Zarqawi, who was killed in a U.S. air strike in Iraq in June 2006.
"He was responsible for organizing and leading Al-Qaeda in Iraq efforts in northern Iraq, including operations against Iraqi and coalition targets in Mosul."
The U.S. military also described Abu Qaswarah as having trained with Al-Qaeda in Afghanistan and been in contact with insurgent leaders in Pakistan. He directed the movement of foreign terrorists into northern Iraq, a position which he took up in 2007, it said.
The attack on the building in Mosul, considered by U.S. commanders as al Qaeda’s last urban stronghold in Iraq, led to the death of four other insurgents as well three women and three children, the military said in an earlier report.
"As coalition forces entered the building housing the terrorist, they began receiving small-arms fire. Coalition forces returned fire once engaged," it said.
"A terrorist detonated a suicide vest shortly thereafter in the house ... Five terrorists along with three women and three children were killed."
Also this month, U.S. forces killed a suspected Al-Qaeda militant believed to have planned some of the deadliest bombings in Baghdad and to have killed a group of Russian diplomats in 2006.
Mahir Ahmad Mahmud al-Zubaydi, also known as Abu Assad or Abu Rami, was killed along with an unnamed woman in Baghdad’s Sunni district of Adhamiyah on Friday, a statement said.
The military said Abu Rami’s group was responsible for suicide bombings in Baghdad on Thursday.
