Turkey says Islamic State was behind a car bombing that killed two police and wounded more than 20 other people in a southern city near the border with Syria.
Turkey's Interior Minister said on May 2 that up to 50 people were detained for questioning in Gaziantep over the May 1 attack there.
Minister Efkan Ala also confirmed the identity of the suicide bomber who blew herself up and wounded 13 people in the city of Bursa last week as 23-year-old Eser Cali.
He described Cali as a member of the outlawed Kurdish Workers' Party, or PKK.
The Kurdistan Freedom Falcons, an off-shoot of the PKK, claimed the Bursa attack in a statement on April 30 and said Cali blew herself up before reaching her intended target.
