ANKARA, Aug. 20 (Xinhua) -- Unidentified assailants fired gun shots at the U.S. embassy in Ankara early Monday, hitting a window of a security cabin but causing no casualties, local media reported.
At least four gunshots were reportedly fired in front of Gate 6 of the embassy from a white car at around 5 a.m. (0200 GMT) local time, broadcaster cnn Turk reported.
Police are searching for the suspects who reportedly fled in a white car before the car's license plate number could be seen.
The embassy is set to close this week for an official public holiday to mark the Eid al-Adha festival.
The attack comes amid high tension between Ankara and Washington over the detention of a U.S. pastor in Turkey. The U.S. diplomatic missions in Turkey have been targeted several times in the past.
