Gunmen attack Russia's Libyan embassy in Tripoli – Russian FM
The Russian embassy in Tripoli, Libya, has come under fire and there were attempts to get into Russia’s diplomatic compound, Russia’s Foreign Ministry said in a statement.
“There has been an incident in Tripoli tonight, in which there was shelling and attempts to enter the territory of the Russian Embassy in this country,” Russian Foreign Ministry spokesman Aleksandr Lukashevich told RT.
According to preliminary information, there are no reports of injuries among the staff.
The ITAR-TASS news agency's witnesses said attackers tore down a Russian flag. The situation was soon brought under control and there are currently no intruders on Russia’s embassy territory. A similar attack on Russia’s Tripoli embassy took place in February 2012 when protesters stormed the compound, condemning Russian and Chinese decisions to block the UN resolution against Syria. No one was injured in that attack.
You're a brave man. Go and break through the lines. And remember, while you're out there risking your life and limb through shot and shell, we'll be in be in here thinking what a sucker you are. ~Rufus T. Firefly
