US forces detained Friday nine suspected members of the al-Qaeda in Iraq group in separate raids in Iraq, while an Iraqi civilian was killed and two others injured in a US airstrike in the south, according to the US military, reported dpa.
The suspects were captured in raids in Baghdad and the northern cities of Bayji and Mosul, a US military statement said.
A suspected leader of a bombing cell within the al-Qaeda in Iraq group was among the detainees.
In the southern city of Nasiriyah, a joint US-Iraqi airstrike targeting the house of a suspected member of a "special group" trained in Iran was carried out, US military spokesman Abdel-Latif Rayan told the Voices of Iraq (VOI) news agency.
The joint forces shot dead a man in self-defence when he pointed a weapon at them. Two men were injured in the incident, the spokesman said.
The US military uses the term special groups to refer to members of Shiite armed groups believed to be trained and armed by Iran.
Earlier, an Iraqi security official told VOI that an Iraqi civilian was killed in a US airstrike in the centre of Nasiriyah, 380 kilometres south of Baghdad.
