GAZIANTEP, Turkey

The death toll in Saturday's terrorist attack on a wedding ceremony in southeastern Turkey’s Gaziantep province rose to 54 Monday, according to a hospital source.

Three more people succumbed to their wounds at hospital, the source, who spoke on condition of anonymity due to restrictions over talking to the media, said.

The attack took place in Beybahce neighborhood of the Gaziantep province’s Sahinbey district at around 10.50 p.m. (1950GMT) on Saturday, according to the Gaziantep Governor's Office.

There has been no claim of responsibility, but Turkish president said early signs point to Daesh's involvement in the attack.

Speaking to reporters in Istanbul Sunday, Recep Tayyip Erdogan said a suicide bomber aged between 12 and 14 was involved in the attack, adding the bomber either blew himself up or was remotely detonated.
