The U.S. military in Iraq says 17 more bodies have been discovered in the northern city of Mosul.
U.S. and Iraqi officials say that in the past two weeks the bodies of more than 50 people, many of them shot execution-style, have been found in and near Mosul. A U.S. military statement says 43 suspected insurgents have been taken into custody in the city since Saturday.
Elsewhere, police say a car bomb explosion in Samarra has killed at least three civilians and wounded several others.
In other developments, Iran has offered to train Iraqi border guards, as part of an effort to help Baghdad strengthen their 1,600-kilometer common border.
Deputy Interior Minister Ali Asghar Ahmadi also said Iran will host a meeting Tuesday of Arab interior ministers, aimed at finding ways to help Iraq quell the insurgency.
