A wave of bombings in Baghdad has killed at least 58 people and wounded more than 100.
Most of the attacks occurred near Shia mosques during Friday prayers in the Iraqi capital.
The BBC reports there were at least six bombings.
One went off near the offices of radical Shia cleric Moqtada Sadr.
A top official blamed al-Qaeda, which in the past has targeted Shia areas.
He said the bombing was in revenge for the recent killing of three senior al-Qaeda leaders by security forces.
