ANKARA- A Kurdish rebel suicide bomber detonated an explosives-laden vehicle outside a police headquarters near Turkey’s border with Syria Wednesday, killing at least three people and wounding some 30 others, the prime minister said. Speaking in Istanbul, Prime Minister Binali Yildirim said the victims of the attack in the town of Midyat, in Mardin province, were a police officer and two civilians. It was not clear if the toll included the suicide bomber. The explosion occurred on a busy main street lined with cafeterias, shops and banks. Television images from the scene showed thick smoke rising from the site of the attack, which destroyed the facade of the police headquarters building.
