Turkish 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 says the man took out a pump action shotgun he hid in his coat and fired around eight shots in the air early on Monday.
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 exhibit in Ankara.
The embassy said its missions in Ankara, Istanbul and the southern city of Adana would be "closed for normal operations on Tuesday."
