Baghdad  - Three policemen were killed and four wounded Sunday in two separate attacks in Mosul.

Gunmen fatally shot three policemen in the city centre, a police source said.

The policemen were shot in a popular restaurant near their patrol vehicle, the source told Voices Of Iraq (VOI) news agency.

A car bomb wounded another four policemen on patrol in southern Mosul, the Iraqi news agency reported.

In a separate incident Saturday night, a roadside bomb killed a US soldier in eastern Baghdad, coalition forces confirmed Sunday.

Saturday's bombing was the second in eastern Baghdad in two days. On Friday, a roadside bomb killed one Iraqi civilian and wounded six others in the eastern Baghdad neighbourhood of Kamaliya, Iraqi police said.

Saturday's bombing brings the number of US soldiers killed in Iraq this month to three.

Some 4,224 US soldiers have been killed in Iraq since the beginning of the US-led invasion in 2003. dpa
