Turkey's interior minister says a car bombing that killed two police officers and wounded 22 other people in the southern city of Gaziantep, near Syria, was carried out by militants linked to the Islamic State group.

Minister Efkan Ala told reporters on Monday that up to 50 people were detained for questioning in Gaziantep over Sunday's attack.

The minister 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 Sunday and said Cali blew herself up before reaching her intended target.
