Russia is denying claims that it is continuing military operations inside Georgia, in violation of an EU-brokered ceasefire.
Amid numerous claims and counter claims, Georgia said Russian armour and soldiers had been seen inside the Georgian city of Gori, several kilometres from the border with South Ossetia.
However this was denied by Russia, which said it had set up two checkpoints near an an abandoned ammunition depot outside the town.
Russia's far greater military might has been evident against Georgia, which last Thursday launched an unsuccessful strike to try to retake the breakaway region of South Ossetia, provoking retaliation from Moscow.
Georgian President Mikheil Saakashvili has already accused Russian forces of violating a ceasefire with troop movements around the country.
In comments broadcast by Georgian television, he insisted that Russian forces were continuing operations in Georgia despite the ceasefire.
Russia says 1,600 civilians died during the violence in South Ossetia, though the figure has not been independently verified.
Moscow's General Staff says it lost 74 soldiers in the fighting, with 171 wounded and 19 missing. Tbilisi puts its death toll at over 175, with hundreds injured. That figure does not include South Ossetia.
Meanwhile, US President George Bush says he is concerned about the reports of continuing Russian military actions.
He told a news conference Russia 'must keep its word and act to end the crisis.' He also said he was sending Secretary of State Condoleezza Rice to Paris and then to Tbilisi for urgent talks.
EU foreign ministers agree on peacekeeping
Separately, foreign ministers have agreed on the EU's role in peacekeeping in Georgia.
The draft statement says that the council believes the EU must be ready to play a role, also on the ground, to support all the efforts, including those of the UN and the OSCE, for a peaceful and lasting resolution of the conflicts in Georgia.
The ministers were debating what consequences to draw from the conflict between Russia and Georgia over South Ossetia after EU president France brokered a peace plan to end the fighting.
French President Nicolas Sarkozy's diplomatic success may make it easier for the EU to set aside deep differences over who to blame for the war in the breakaway Georgian region, although some member states were expected to seek symbolic sanctions against Moscow.
The conflict again highlighted EU divisions over how to deal with Russia which have dogged ties with Moscow since the bloc's eastward enlargement to embrace ex-communist central European states in 2004.
Poland and the Baltic states, wary of a resurgent Russia using its muscle to dominate neighbours, have condemned what they call Moscow's aggression against Georgia and wanted the EU to take a tough line.
Irish Rapid Reaction Corps on standby
Ireland has told its EU colleagues that members of its Rapid Reaction Corps are on standby to travel to Georgia to help assist in the humanitarian crisis there.
The Government has also said it will contribute €100,000 to the Red Cross to help its humanitarian operations in the region.
The announcement was made by Minister of State at the Department of Foreign Affairs, Peter Power, as the special meeting of EU foreign ministers on the crisis in South Ossetia came to an end.
Mr Power said EU member states had emphatically and unanimously endorsed the peace initiative led by the French Presidency, and agreed to by the Georgian and Russian governments.
He said the plan would provide a basis for more meaningful negotiations to take place. He added that on another level, it showed how the EU and Europe acting with one voice could be a powerful actor on the world stage.
He said the view at the meeting was that the EU should not get involved in apportioning blame. He also said the possibility of EU peace monitors travelling to the region was only briefly discussed.
Mr Power said the meeting also addressed the issue of how best to get humanitarian aid into the region.
