>>> Bombing at wedding in southern Turkey kills at least 30
The attack was the deadliest in a series of bombings in Turkey this year, and President Tayyip Erdogan said on Sunday Islamic State was likely behind it. Turkey faces multiple security threats from militants at home and from Syria.
"Initial evidence suggests it was a Daesh attack," Erdogan said, using an Arabic name for the hardline Sunni group, during a visit to Gaziantep after the attack. He said 69 people were in hospital and 17 were "heavily injured".
Islamic State has been blamed for other attacks in Turkey, often targeting Kurdish gatherings in an effort to inflame ethnic tensions. The deadliest one was last October, when suicide bombers killed more than 100 people at a rally of pro-Kurdish and labour activists in Ankara.
Saturday's wedding party was for a member of the pro-Kurdish Peoples' Democratic Party, it said, and the groom was among those injured. The bride was not hurt, one local official said.
Hundreds gathered for funerals on Sunday, some weeping at coffins draped in the green colour of Islam, local television images showed. But other funerals would have to wait because many of the victims were blown to pieces and DNA forensics tests would be needed to identify them, security sources said.
In Gaziantep, the chief prosecutor's office said they had found a destroyed suicide vest at the blast site.
