At least 50 people have been killed and 73 wounded in the bombing of a wedding in Gaziantep Province in southeastern Turkey.

President Recep Tayyip Erdoğan said, “Daesh [the Islamic State] is the likely perpetrator of the attack,”, while Deputy Prime Minister Mehmet Simsek said it appeared to be a suicide bombing.

Erdoğan declared, “Our country and our nation have again only one message to those who attack us: You will not succeed!” He then linked the Islamic State, the Turkish Kurdish insurgency PKK, and the July 15 coup attempt, which he blames on the US-based cleric Fethullah Gülen:

There is no difference between the PKK [Kurdistan Worker’s Party] which martyred 70 security personnel last month, the FETÖ [“Fetullahist Terror Organization”] as an actor in the July 15 coup bid claiming 240 people, and the possible [perpetrator] of the Gaziantep terror attack, Daesh.

Gaziantep, about 60 km (37 miles) from the Syrian border, is a hub for both refugees and members of Syrian rebel factions. The district where the bombing occurred has a large Kurdish population.

The pro-Kurdish Peoples’ Democratic Party (HDP) said the wedding was for one of its members, and women and children were among those killed.

Both the Islamic State and the PKK have carried out deadly bombings throughout Turkey over the past year.
