Dozens killed in Baghdad in 'revenge al-Qaeda attacks'
The wave of bombings wreaked widespread destruction
A wave of bombings in the Iraqi capital, Baghdad, has killed at least 58 people and wounded more than 100.
Most of the attacks occurred near Shia mosques during Friday prayers. At least two 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 had been carried out in revenge for the recent killing of three senior al-Qaeda leaders by security forces.

No group has publicly said it carried out the attacks, but many will look at the pattern of Friday's bombings - all near groups of Shia worshippers, all around the time of Friday prayers - and draw their own conclusions.
The Baghdad authorities have blamed al-Qaeda, saying the bombings were in revenge for the killing of high-profile al-Qaeda operatives on Sunday.
Whoever did carry out the attacks, it is hard not to conclude that they were designed to inflame tensions between Iraq's Sunni and Shia communities at a time of political uncertainty.
