A car bomb exploded outside a popular ice cream shop in central Baghdad just after midnight Tuesday, killing 13 people and wounding 24, hospital and police officials said.

The Islamic State militant group claimed responsibility for the attack, which Iraqi officials said involved apparently remotely detonated explosives inside a parked car. The officials spoke on the condition of anonymity in line with regulations.

The attack came just days into the holy month of Ramadan, when Muslims fast during daylight hours. After sundown, families break their fast, and Baghdad’s restaurants and cafes quickly fill.

Videos posted to social media showed chaotic scenes on the streets surrounding the blast. Some wounded people lay on the ground; others propped themselves up on the colorful park benches outside the ice cream shop. A young girl, wearing a ribbon and bow in her hair, wandered the scene dazed.

Ramadan is often marked by an uptick in violence in Iraq.

Last year, Baghdad was rocked by a huge truck bomb attack that targeted a popular retail district in the city center where young people and families were shopping for new clothes ahead of the holiday that marks the end of Ramadan. The blast killed hundreds in the single deadliest event in Baghdad since Saddam Hussein was toppled in 2003. The Islamic State group also claimed responsibility for that bombing. Tuesday’s attack comes as Iraqi troops are slowing pushing Islamic State fighters out of their last strongholds in the northern city of Mosul.
