Car bombs near Shiite places of worship, known as husseiniyahs, in north Baghdad killed at least 12 people and wounded at least 50 on Tuesday, officials said.

A medical official put the toll from the attacks in the Iraqi capital at 12 dead and 50 wounded, while an interior ministry official said the three car bombs killed 19 people and wounded 72.

Differing tolls are common in the confusion following attacks in Iraq.

There was no immediate claim of responsibility for the attacks, but car bombs are a hallmark of Sunni insurgents who often carry out attacks against Iraq's Shiite majority.

Violence in Iraq has decreased dramatically from its peak in 2006 and 2007, when brutal sectarian violence swept the country, but attacks remain common. - Sapa-AFP
