A youth shot dead three Turkish police officers and wounded three others at a bus station in the city of Sanliurfa in southeast Turkey before he was also shot dead, the Anadolu Agency reports.
The Sanliurfa Governor Gungor Azim Tuna said that the shooting was not terrorism-related. It was not clear when it occurred.
He added that the attacker was a 17-year-old with psychological problems who was traveling with his family and who had taken his father's gun.
The youth opened fire on three police officers as they asked people at the bus station for their identify papers and then fled before opening fire on another group of police. Three of the officers later died in hospital, Reuters reports.
