BBC: Gunmen kill 10 policemen in Iraq

Iraqi capital shaken by attacks

A suicide bombing in central Baghdad has killed at least three Iraqis and wounded more than 40 other people.

Police say the bomber appeared to be targeting an American military patrol in Tayaran Square.

Before the area was sealed off by troops, eyewitness reports said US soldiers might be among the wounded.

Earlier, 10 Iraqi policemen and a number of civilians were killed in a spate of drive-by shootings, most of them in the capital.
