A number of bombing attacks have been reported in Iraq.
In Baquba, at least ten people were killed in an apparently co-ordinated series of attacks. Local sources said a suicide car bomb and mortars were used.
Police in the town, 65km northeast of Baghdad, said the insurgent attack began when five Iraqi soldiers were killed in an ambush outside Baquba.
A suicide car bomb later targeted police heading to reinforce the area, killing two policemen and wounding 12 people.
Two roadside bombs killed three soldiers and at least one mortar round landed in the town, police also said.
In the town of Balad, north of Baghdad, 15 people described as civilians were killed and at least 23 were wounded when a bomber blew up his car near an Iraqi army patrol.
