Police have detained a man who fired shots in front of the US embassy in Ankara, several hours after the Russian ambassador to Turkey was killed in an attack.
The state-run Anadolu Agency said the man took out a pump action shotgun he hid in his coat and fired around eight shots in the air early on Tuesday. He was overpowered by the embassy's security guards.
No-one was hurt in the incident which occurred hours after a Turkish policeman, appearing to condemn Russia's military role in Syria, fatally shot Russian Ambassador Andrei Karlov in front of a shocked gathering at a photo exhibition in Ankara.
The embassy said its missions in Ankara, Istanbul and the southern city of Adana would be "closed for normal operations on Tuesday".
