At least 25 people were killed and dozens wounded on Monday in a double bomb attack in a market in a Sunni district of Baghdad.
Reports say the first bomb went off in a car or a bus in the district of Adhamiyah and the next one exploded seconds later as a crowd of people gathered to help the victims.
Nearly 50 people have been reported injured in the blasts, which took place in the morning rush hour.
It is one the deadliest attacks in Iraq in months as violence recedes from the peaks recorded two years ago.
Adhamiyah, a Sunni neighbourhood in the mostly Shi'ite eastern half of the city, was the scene of fierce clashes at the height of Iraq's sectarian violence.
