At least 50 people were killed in a southeastern Turkish city close to Syria when a suspected suicide bomber linked to Islamic State jihadists attacked a wedding thronged with guests, officials said Sunday.
Turkish President Recep Tayyip Erdogan said the IS extremist group was the "likely perpetrator" of the bomb attack, the deadliest in 2016, in Gaziantep late Saturday that targeted a celebration attended by many Kurds.
The remains of a suicide vest were found at the scene, the chief prosecutor's office said in a statement on Sunday, broadcaster CNN-Turk reported.
The explosion was the latest attack to rock the key NATO member in a horrific year that has seen strikes blamed on Kurdish and Islamist militants as well as a bloody July 15 botched coup.
Gaziantep governor Ali Yerlikaya said in a statement that 50 people had been killed, raising a previous toll of 30. He had previously said 94 were wounded in what he described as an "abhorrent terror bomb attack on a wedding".
Erdogan said in a statement there was "no difference" between the group of US-based preacher Fethullah Gulen whom he blames for the failed coup bid, the outlawed Kurdistan Workers Party (PKK) "and Daesh (IS), the likely perpetrator of the attack in Gaziantep".
"Our country and our nation have again only one message to those who attack us -- you will not succeed!" he said.
World leaders quickly condemned the attack including French President Francois Hollande who denounced the "vile" incident.
"France stands with all who fight against the scourge of terrorism," the presidency said in a statement.
The US ambassador to Turkey John Bass condemned the "barbaric attack on innocent civilians", adding that Washington would "continue to work closely together to defeat the common threat of terrorism" in a statement shared on the official US embassy in Turkey Twitter account.
- Kurds targeted -
Reports said the wedding had a strong Kurdish presence. The Dogan news agency said the bride and groom were from the mainly Kurdish region of Siirt further to the east and had themselves been uprooted due to the flare-up in violence with Kurdish militants.
The pro-Kurdish Peoples' Democratic Party (HDP) said its members had been present at the wedding which was also attended by many women and children.
The Hurriyet daily said the bride and groom -- Besna and Nurettin Akdogan -- were in hospital but their lives were not in danger.
Erdogan said the aim of such attacks was to sow division between different groups in Turkey including Arabs, Kurds and Turkmen and to "spread incitement along ethnic and religious lines".
Many jihadists see Kurds as one of their main enemies, with Kurdish militias playing a significant role in the fight against IS on the ground in Syria.
Prime Minister Binali Yildirim said Gaziantep would show the same spirit it had shown in 1921, when it defeated French forces in Turkey's Independence War which led to the word Gazi (war hero) being added to its original name of Antep.
"Our grief is great, but be sure our unity and togetherness will defeat all these diabolic attacks," he said.
- 'Happiest day poisoned' -
Mehmet Erdogan, a ruling Justice and Development Party (AKP) lawmaker for Gaziantep said there was a "high possibility" it was a suicide attack, comments echoed by Deputy Prime Minister Mehmet Simsek.
Dogan news agency said the suicide bomber had mixed in with the guests before detonating the charge. Security forces are now searching for two individuals who entered the celebration with the suspected bomber and then fled, it added.
Gulser Ates, who was wounded in the attack, told Hurriyet the attack took place as the party was breaking up.
"We were sitting on chairs, having a chat with one of our neighbours.
"During the explosion, the neighbour died on top of me. I remember being underneath. If my neighbour hadn't fallen on top of me, I would have died," she said.
"The bride and groom's happiest day was poisoned."
Another resident in Gaziantep told Dogan that when he arrived, he saw many dead bodies and body parts including a "head, arm, hand scattered on the ground".
Meanwhile, images on broadcaster CNN-Turk showed rows of coffins covered in white sheets for the funerals of some of those killed.
Crowds of mourners gathered to pray, and chants of Allahu Akbar ("God is greatest") could be heard.
