At least 51 people have been killed and nearly 100 wounded in a suspected suicide bomb attack on an outdoor Kurdish wedding celebration in Gaziantep, Turkish authorities have said.
In a rare show show of agreement with Turkey's government, Turkey pro Kurdish party, the HDP, also blamed ISIS for the terrorists attack.
The bomb went off in a part of town popular with students and which has a large Kurdish community.
Local MP Mahmut Togrul told the Reuters news agency it had been a Kurdish wedding. Mr Togrul's party, the pro-Kurdish Peoples' Democratic Party (HDP), said the wedding had been for one of its members.
Turkey has been hit by a series of bombs both by IS and Kurdish militants in the past year. The last IS attack, on Istanbul airport in June, killed more than 40 people.
Overall in the last three months, some 200 Turkish people have been killed in terrorist attacks, and over 300 people were killed in the failed military coup.
