At least 55 people were killed on Sunday in a wave of car bombings in Shia neighborhoods in Iraq’s capital Baghdad and a suicide bombing which targeted soldiers in the north of the country.

Eleven cars rigged with explosives blew up in predominantly Shia Muslim areas in and around Baghdad, killing 41 people.

The bombs, placed in parked cars and detonated over a half-hour period, targeted commercial areas and parking lots.

The deadliest attack was in the town of Nahrawan, south of the capital, when two car bombs exploded moments apart near a busy market and left seven dead. Six civilians were killed and 15 wounded in the northern Shaab neighborhood, while other blasts hit Mashtal, Sab al-Bor, Hurriyah, Baladiyat, and Ur.

In the northern city of Mosul, a man drove a car outside a government bank, where soldiers were waiting to collect their salaries, and detonated it. At least 14 people were killed.

More than 600 people have died this month and almost 600 this year amid the worst violence since 2008.
