50 people were killed and dozens were wounded when a suspected suicide bomber detonated his explosives among people dancing on the street at a wedding party in the southern Turkish city of Gaziantep on Saturday, security and hospital sources said.
President Tayyip Erdogan said it was likely that Islamic State militants had carried out the late-night attack, one of the deadliest this year in Turkey, which faces threats from militants at home and across the border with neighboring Syria.
"The celebrations were coming to an end and there was a big explosion among people dancing," said 25-year-old Veli Can.
"There was blood and body parts everywhere."
Deputy Prime Minister Mehmet Simsek said the "barbaric" attack in the city of Gaziantep, near the border with Syria, appeared to be a suicide bombing.
On Sunday morning, President Tayyip Erdogan confirmed the death toll and condemned the attack, saying it was likely carried out by Islamic State militants.
The attack appeared to have hit when a large group of people from a wedding party took to the streets in celebration.
