Istanbul, Turkey : Authorities on Sunday released four suspects detained after a deadly bomb attack in a predominantly Kurdish city of southwest Turkey, a local official said, according to AP.
The bomb, which had been packed in a parked car, exploded Thursday in Diyarbakir as a military bus carrying soldiers passed by. Five people were killed, including four students who were studying at a nearby building for university entrance exams, and 68 people were wounded, including more than 30 soldiers.
No one claimed the attack, but Turkish officials quickly blamed separatist Kurdish rebels. Prime Minister Recep Tayyip Erdogan said Saturday that the attack, in which plastic explosives were used, bore the hallmark of the rebel Kurdistan Workers’ Party, or PKK.
Police detained four suspects, but gave no information about who they were or why they were suspected. An official said Sunday that the four had been released, but did not elaborate.
