A suicide bomber has struck a park in the Iraqi capital, killing at least 25 people, officials said.
The bomber detonated an explosives-rigged belt in the Qahira area of north Baghdad on Friday, also wounding dozens of people.
Children were among the casualties, security sources said, and the wounded were taken to four different hospitals.
Police said the attack took place in a park that has several cafes and restaurants.
It was one of the worst recent bombings in Iraq. Fighters have carried out a number of attacks at night in recent weeks, striking cafes and other places where crowds of people gather, to inflict maximum casualties.
Attacks across the country have killed more than 3,580 people since the beginning of 2013.
Some analysts and diplomats link the increased bloodshed to anger among Iraq's Sunni Arab minority over their alleged ill-treatment at the hands of the Shia-led government.
But Prime Minister Nouri al-Maliki has vowed to press on with the security force operations, insisting they are producing results, pointing to the arrest of hundreds of alleged fighters and the killing of dozens of others.
