BAGHDAD, Iraq (CNN) -- Eleven people from an Iraqi family, including women and children, were killed Sunday during a raid involving U.S. troops, Iraqi police sources said.
The U.S. military said the deaths were caused by a suicide bomber, but the Iraqi police sources said it was not clear how the family died.
A U.S. military statement said troops entered a building in the northern Iraqi city of Mosul looking for a terrorist suspect.
Troops in the building were shot at, the statement said, and returned fire.
The suspect then detonated a suicide vest, the statement said.
Those killed included three women, three children and five people whom the U.S. military referred to as terrorists, according to the statement.
Two children, one of whom was injured, were found near the building and were moved to a safe location, the coalition statement said.
Troops also found a hidden cache of weapons in the building, containing small firearms and explosives, the statement said.
"This is just another tragic example of how al Qaeda in Iraq hides behind innocent Iraqis," said Rear Adm. Patrick Driscoll, Multi-National Force-Iraq spokesman. "The terrorist exploded his suicide vest in close proximity to women and children, and in a house full of explosives and weapons."
In a separate attack in Mosul, at least four Iraqis were killed and six others wounded Sunday by gunmen who fired on a group gathering at a mourning tent, an Iraqi Interior Ministry official said.
Mourning tents are typically erected after funerals, but it was unclear if this incident occurred at a funeral.
Last month four employees of Iraqi satellite TV station Al-Sharqiya were abducted and killed in the same neighborhood.
Elsewhere Sunday, a member of the Sons of Iraq was killed and another wounded during an ambush in Diyala province. The Sons of Iraq is a group of former Sunni insurgents who have turned against al Qaeda in Iraq.
The attacks came the same day that Iraqi officials met with the foreign minister of Egypt.
Officials from both countries said Egypt is looking to re-establish its diplomatic presence in Baghdad as the country's foreign minister visits Iraq.
Foreign Minister Ahmed Aboul Gheit arrived in Baghdad on Sunday, the first such visit in 18 years.
The last time an Egyptian foreign minister went to Baghdad was in 1990, before Iraq invaded Kuwait.
Gheit met with his Iraqi counterpart, Foreign Minister Hoshyar Zebari. According to an Iraqi Foreign Ministry official, talks also involved Iraqi Prime Minister Nuri al-Maliki and Egyptian oil ministers.
The leaders discussed ways to improve diplomatic relations now that the security situation has improved in Iraq, the official said.
The talks also included discussions of bilateral cooperation in investment, trade and transport.
In July 2005, militants kidnapped Egypt's ambassador, Ihab al-Sherif, from a Baghdad street and killed him.
Al Qaeda claimed responsibility for the assassination, saying it had killed al-Sherif because of Egypt's foreign policies and its relationships with the United States and Israel.
Since then, no ambassador from an Arab country has been stationed permanently in Iraq.
Egypt follows in the footsteps of several other Arab countries which are re-strengthening their diplomatic ties with Iraq with the security situation in the country showing improvement.
Bahrain, Syria, the United Arab Emirates and Jordan have already named ambassadors to Iraq.
