GORI (Georgia), Aug 9: Georgia called for a ceasefire on Saturday after Russian bombers widened an offensive to force back Georgian troops seeking control over the breakaway region of South Ossetia.

US President George W. Bush said Russian attacks on Georgia marked a “dangerous escalation” of the crisis and urged Moscow to halt the bombing immediately.

Russian President Dmitry Medvedev told Bush the only solution was for Georgian troops to quit the conflict zone.

Russia said it had seized the rebel capital, Tskhinvali, but Georgia denied the claim on the second day of fighting that threatens oil and gas pipelines seen as crucial in the West.

Russian officials said the death toll now stood at 2,000 and 30,000 refugees from South Ossetia had fled to Russia over the past 36 hours. Russia said two of its warplanes had been shot down, 13 of its soldiers killed and 70 wounded.

“I call for an immediate ceasefire,” Georgian President Mikheil Saakashvili said in Tbilisi. “Russia has launched a full scale military invasion of Georgia.”

Russia’s military response to the crisis dramatically intensified a long-running stand-off between Russia and the pro-Western Georgian leadership that has sparked alarm in the West and led to angry exchanges at the United Nations reminiscent of the Cold War.

STATE OF WAR: Georgia’s parliament approved a state of war across the country for the next 15 days, while Russia accused the West of contributing to the violence by supplying Georgia with arms.
