Russia's embassy in the Libyan capital of Tripoli came under attack this evening after a group of people tried to force their way into the compound.
A diplomatic source in Libya said security guards fired shots to disperse around 60 people that had approached the embassy.
The compound was quickly secured by guards and according to the Russian Foreign Ministry no diplomats were wounded in the incident.
The reason for the attack was not clear, but one diplomatic source said it did not appear to be directly linked to any militant group.
He said a Ukrainian woman had killed a Libyan yesterday and then sought refuge in the Russian embassy.
The crowd had then come to protest and look for her.
The Russian Itar Tass news agency cited unnamed sources as saying that the embassy territory was now fully under control.
There have been a number of attacks on Western diplomatic missions since the overthrow of Muammar Gaddaffi two years ago, the worst being directed against the US consulate in Benghazi.
Militants linked to al-Qaeda attacked the consulate and killed US ambassador to Libya Christopher Stevens and three other Americans on 11 September 2012.
Western powers, using air power, led the military campaign that ultimately toppled Gaddafi.
Russia, however, did not take part in the action and condemned what it called the West's abuse of a United Nations Security Council to intervene.
