US warship docks in Georgia port

The USS McFaul is the first of three ships to arrive in Georgia

A  has arrived in the Georgian port of Batumi carrying the first delivery of aid supplies by sea.

Russian forces are still in control of the military port of Poti, to the north of Batumi, after withdrawing most of its combat troops from the country.

French President Nicolas Sarkozy, who brokered the ceasefire, has urged Moscow to pull out those forces too.

Meanwhile, a train carrying fuel has exploded after hitting a mine near Gori, Georgia’s interior ministry said.

A huge plume of black smoke could be seen across the region, the AFP news agency reported.

Interior ministry spokesman Shota Utiashvili said there had been several explosions near an abandoned Georgian military base where the Russian troops, on leaving Gori, had left a stockpile of munitions taken from the Georgian army.

“Our teams can’t even get close to the area because it is in flames and the munitions are continuously exploding,” he said.

The spokesman suggested the stockpile or the train track could have been mined by the Russian forces. There have been no details about possible casualties.

Georgian authorities had been hoping to help thousands of refugees return to Gori on Sunday having carried out a mine-sweeping operation in the town.

Russia’s four-day war with Georgia erupted after Tbilisi tried to retake its province of South Ossetia – which broke away in 1992 and was supported by Moscow – in a surprise offensive on 7 August. The offensive followed a series of clashes between Georgian and South Ossetian forces.

The conflict left hundreds of people dead and created tens of thousands of refugees. Many have been returning to their damaged or destroyed homes since the Russian withdrawal.

The UN’s refugee agency UNHCR reported this week that, according to Russian estimates, more than 30,000 people from South Ossetia had fled to North Ossetia. Another 128,000 were estimated to have been displaced within Georgia.

International aid agencies are working on the ground and the US has already delivered some aid by military cargo plane.

The destroyer USS McFaul is reported to be carrying supplies such as blankets, hygiene kits and baby food.

Two more US ships are due to dock later this week.

The BBC’s Gabriel Gatehouse, in Tbilisi, said that apart from delivering aid, the arrival of US naval personnel is undoubtedly intended to send a signal to the Russians – that America is serious about its support for Georgia.

But, he adds, the prospect of US and Russian armed forces actually meeting on Georgian soil is one that both sides seem keen to avoid.

Batumi is not a natural harbour for a naval vessel the size of the USS McFaul to dock but Russian forces have been fortifying their positions at the key port of Poti, further up the coast.

On Saturday, Mr Sarkozy, welcomed the withdrawal of Russian forces so far, but urged Moscow to pull its troops back from Poti and Senaki, which is the site of Georgia’s main air base.

Russia says it has a duty and a right to keep its forces in a buffer zone around the breakaway territories of Abkhazia and South Ossetia – though it acknowledges that Poti falls well outside that zone.

Russia to keep posts in Georgia

A senior Russian general says Moscow intends to maintain a military presence of more than 2,000 troops in Georgia.

Gen Anatoly Nogovitsyn said Russian forces would be stationed around the breakaway regions of Abkhazia and South Ossetia, the focus of recent conflict.

Correspondents on the ground say they have seen what appears to be a significant troop movement from Georgian positions to South Ossetia.

Georgia has said it will not accept any “annexation” of its land by Russia.

Russia’s land forces commander earlier said that all Russian combat troops would be moved back from Georgia proper to South Ossetia by the weekend and that most of the soldiers sent to the region as reinforcements would return to Russia within 10 days.

Correspondent says he has witnessed hundreds of Russian armored vehicles, including tanks and armored personnel carriers, withdrawing from the town of Igoeti, about 35km (21 miles) from the Georgian capital, Tbilisi.

Our correspondent says buses of Georgian police are arriving to take control after Russian troops removed their road block and pulled out.

There are also reports of a pull-back from the Georgian flashpoint town of Gori to South Ossetia.

‘Snail’s pace’

At a briefing in Moscow, the deputy chief of the Russian military general staff, Gen Nogovitsyn, said the withdrawal of all combat troops was going according to plan.

“The troop pull-back has been started at a rate to make sure that the Russian troops be within the zone of responsibility of the Russian peacekeeping contingent by the end of 22 August,” he said.

“We are not going to correct this plan or increase the speed of withdrawal.”

Gen Nogovitsyn said Russian troops were setting up checkpoints on the borders of South Ossetia and Abkhazia with Georgia.

The so-called zone of responsibility also includes Georgia’s main airbase at Senaki, and cuts across Georgia’s main east-west highway, which stretches from Tbilisi to the Black Sea.

Russian officials say the zone was established in principle in an agreement between Russia and Georgia which pre-dates this month’s conflict, but was never put into force.

Georgian State Minister for Reintegration Temur Iakobashvili told Reuters that such a zone was “a violation of any agreement”.

Russia’s four-day war with Georgia began after Tbilisi tried to retake the Moscow-backed breakaway province of South Ossetia on 7 August, following days of clashes with separatists.

The fighting ended with an EU-brokered ceasefire deal, and a promise by Moscow to pull back its forces by 22 August.

But the commander of US forces in Europe, Gen John Craddock, said Russia was taking too long to pull back, saying “if they are moving, it is at a snail’s pace”.

The first of the Russian Black Sea Fleet warships, which have been deployed off the west coast of Georgia’s province of Abkhazia, has returned to its base at Sevastopol in Ukraine.

Ukraine’s President Viktor Yushchenko criticised Russia’s use of ships from the base leased to Moscow, saying there was a danger of his country being passively drawn into an international conflict against its will. Protesters reportedly greeted the ship’s return on Friday.

The United Nations High Commissioner for Refugees, Antonio Guterres, has arrived in the capital of South Ossetia, Tskhinvali, to assess the humanitarian situation there.

Thousands of civilians are reported to be in urgent need of relief supplies.

The UN estimates that nearly 160,000 people have been displaced across the whole of Georgia since the conflict began.

The Georgian government is seeking $1-2bn (£0.5-1bn) in aid to repair and develop infrastructure following the conflict with Russia, the head of the US government aid agency, USAid, said. The World Bank has also announced that it is sending a team of experts to the country to assess its reconstruction needs.

‘War with Nato’

Diplomatic efforts at the UN have reached deadlock over rival resolutions on the crisis from France and Russia.

Thousands of civilians are reported to be in urgent need of relief supplies

Russia has reiterated its opposition to a rival French text, which reaffirms Georgia’s territorial integrity.

Georgia’s President Mikhail Saakashvili told the BBC he would never accept what he called Russia’s “annexation of its territory”.

He warned that Russia’s involvement in South Ossetia, Abkhazia and Georgia were intended to send a strong message to the West.

“If Nato fails now to come up with a united response, nobody’s safe, even if they are in Nato already,” he said.

“It’s all about reconsidering the role of Nato, the role of international law and borders in this part of the world. This is no longer about Georgia anymore.

“Russia decided to win war with Nato without firing a single shot at it.”

A Nato spokeswoman says Russia’s defence ministry has decided to halt all military co-operation with the bloc to protest at what Moscow calls the alliance’s biased, pro-Georgian view of the conflict.

The move by Moscow followed a Nato statement that there would be no “business as usual” with Moscow unless its troops pulled out of Georgia.
