Iraqi officials say a double car bombing has killed at least 57 people and wounded about 150 in central Baghdad.
Officials say the devastating attack involved a suicide bomber in a van and a parked vehicle, which exploded in quick succession in Baghdad's Tayaran Square.
Authorities say the suicide bomber drove into the square this Tuesday morning and pretended to offer work to poor laborers, mainly Iraqi Shi'ites. He then set off the explosives in his vehicle after attracting a large crowd.
Laborers typically gather in Tayaran Square to wait for jobs in construction, cleaning and painting. The blast also destroyed scores of small stands providing food to the workers.
Iraqi Prime Minister Nuri al-Maliki condemned the attack as "horrible" and blamed it on sympathizers of former dictator Saddam Hussein and Sunni extremists.
On Monday, Iraqi officials reported more than 60 people killed or found dead in the Baghdad area and northern Iraq.
