Two bombs exploded Saturday in a busy marketplace in central Baghdad, killing at least 25 people, Iraqi officials said.
Authorities said at least 50 people were wounded in the attack in the al-Sinaq neighborhood. They said the death toll was likely to rise.
At least one of the explosions was caused by a suicide bomber. The second blast went off minutes later.
The Associated Press reported that the Islamic State group claimed responsibility for the attack, which it said involved two suicide bombers.
Baghdad has been on high alert since October, when its military started an offensive to retake the northern jihadist stronghold of Mosul.
