At least three Turkish police officers have been killed in a suicide bomb attack in Gaziantep, southeastern Turkey on Sunday. Reuters cites security sources saying that the bomb exploded during a police raid on a suspected Islamic State (IS, formerly ISIS/ISIL) safehouse. Eight people were reportedly injured in the blast. In August, at least 50 people were killed and scores more injured when a suicide bomber targeted a wedding ceremony in Gaziantep. The attacker was suspected of IS links, according to Turkish authorities.
