TOPSHOT - Relatives grieve at hospital August 20, 2016 in Gaziantep following a late night militant attack on a wedding party in southeastern Turkey. Turkish President Recep Tayyip Erdogan on Sunday said the Islamic State (IS) group was the "likely perpetrator" of the bomb attack. Erdogan said in a written statement that there was "no difference" between the group of US-based preacher Fethullah Gulen who he blames for a failed July 15 coup bid, the outlawed Kurdistan Workers Party (PKK) "and Daesh (IS), the likely perpetrator of the attack in Gaziantep". / AFP / AHMED DEEB (Photo credit should read AHMED DEEB/AFP/Getty Images)
