Two attackers shot at the U.S. consulate in Istanbul on Monday, but managed to escape the scene after police returned fire.
There were no reports of injuries from the attack.
Turkish media said later that one of the assailants, a woman, had eventually been detained by police.
The consulate attack came hours after a bomb exploded at a police station in another section of Turkey's largest city, wounding at least 10 people, including three police officers.
The state-run Anadolu news agency quoted the Istanbul police blaming the attack on "terrorists."
Following the blast, police were later involved in an exchange of gunfire with two attackers at the site that left both of them dead.
