Turkish police killed one attacker who tried to enter the main police station in the southeastern city of Gaziantep on Tuesday, while a second was still at large, Turkish Deputy Prime Minister Numan Kurtulmus said.
There was "an armed attack" at a security checkpoint outside the police headquarters in Gaziantep, the provincial governor's office said in a statement.
An officer was lightly wounded in the shootout, but police responded immediately and shot the suspect dead, the statement added.
Later during the day, a police patrol vehicle was also attacked by three assailants in Gaziantep. One of the attackers was apprehended by the policemen while a search for two others went under way.
