At least 30 people have been killed in what has been described as a "barbaric" bomb blast at a wedding in south-eastern Turkey.

Authorities in the city of Gaziantep,  near the border with Syria, say 94 people have been injured in the blast.

Turkish President Recep Tayyip Erdogan has condemned the attack saying it is likely Islamic State militants carried out the late-night bombing.

The bomb detonated when a large group of people from the wedding party took to the streets in celebration.
