Calls for a halt to sectarian violence went unheeded, with gunmen storming the home of a top police anti-terrorism official and killing him, his wife and their two young children. The BBC said police Capt. Adnan Ibrahim was targeted by Sunni gunmen.
Gunmen killed Assad Nassir, a Sunni cleric, outside his home later in the day and, in a third incident Saturday, eight police officers were kidnapped at a checkpoint in Ramadi, a city west of Baghdad.
In the northern city of Mosul, two police officers were shot at a checkpoint and two more died when a roadside bomb detonated, the BBC said.
The attacks came after three explosions Friday in Sunni-occupied areas of Baghdad killed an estimated 60 people.
