INSURGENTS fired rocket-propelled grenades at the home of an Iraqi police officer yesterday, killing his four children and his brother and wounding his wife.

Bomb blasts, shootings and rocket-propelled grenade attacks killed at least 13 people throughout Iraq, including a policeman’s four children, officials said today.

Insurgents in western Iraq killed five US Marines and sliced the heads off three Iraqis, part of a group of 21 men whose bodies were found dumped in the desert near the Syrian border after being gagged and shot.
