Earlier in the week after Georgia detained some Russian soldiers, Sergei Lavrov, the Russian foreign minister, ratcheted up the rhetoric when he threatened to "use all means available to us" to secure the release of the detained soldiers, raising fears of military confrontation between the two ex-Soviet neighbours.
The crisis began on Wednesday when Georgian troops surrounded the regional headquarters of Russian troops in the capital Tbilisi and arrested five officers and a driver on suspicion of espionage. This article from the London Telegraph provides the background and current situation.
Russia suspends Georgia pullout

A senior Russian army commander says Moscow is suspending the withdrawal of its forces from Georgia, amid a spying row between the two countries.
Russian forces were to pull out of two bases in Georgia by 2008, but the commander said the security of troops could not be guaranteed as they left.

The worst breakdown in relations between the two ex-Soviet neighbours in 15 years seemed to worsen hour by hour on a day of high drama.
Flouting Kremlin demands for their immediate release, a Tbilisi court ordered the four Russian servicemen, whose arrest on Wednesday ostensibly triggered the crisis, to be detained for a further two months.
Georgian troops seeking a fifth officer, Lt Col Konstantin Pichugin, surrounded the headquarters of the Russian Army Group in the capital Tbilisi for a third day.
The crisis erupted when Georgia arrested the men, claiming they were members of a "very dangerous" network that had spied on the military, caused an explosion that had killed three policemen, and was planning a "serious provocation" on Georgian soil.
