Tbilisi: Georgian riot police used teargas, water cannon and rubber bullets on Thursday to halt five days of demonstrations against President Mikheil Saakashvili, who blamed the unrest on Russia.
At least two people were hit and killed by cars leaving the scene of the clashes, the interior ministry said.
Thousands of riot police dispersed protesters outside parliament in torrential rain just after midnight to clear the way for a military parade celebrating the former Soviet state`s independence.
At least 37 people were injured. Some protesters were beaten by police with batons and a Reuters correspondent and photographers saw people smeared in blood lying restrained on the tarmac. Some protesters wielded metal poles and sticks.
Saakashvili, whose country fought a brief war against Russia in 2008 over two Kremlin-backed rebel regions, pointed the finger at Moscow, Georgia`s longtime master, in a speech during the military parade outside parliament.
"It was an attempt to hold protests in accordance with a scenario written outside Georgia and sought to thwart Independence Day celebrations, cause sabotage and mass disorder in the country," Saakashvili said.
"This day was chosen as a target by our occupiers," he added in a clear reference to Russia, which maintains thousands of troops in the breakaway regions of South Ossetia and Abkhazia and recognized them as independent countries after the conflict.
Standing at the site where the protest was dispersed, Saakashvili addressed 6,000 armed servicemen in crisp new uniforms. Dozens of new armored personnel carriers rolled by, and military planes flew overhead.
Streets leading to the venue were closed.
The pro-Western Saakashvili repeatedly has accused Russia of seeking to undermine him and his country. His remarks may have been aimed in part at prominent opposition leader Nino Burjanadze, who has visited Russia and met senior officials.
Interior Ministry spokesman Shota Utiashvili said one policeman and a protester were hit and killed by vehicles in a convoy leaving the scene.
He said one car carried Burjanadze, who denied the allegation.
Burjanadze, a former ally of Saakashvili`s who has vowed to lead a peaceful revolution against him, said the cars did not belong to her. She called for an investigation and said she would continue to press for Saakashvili to quit.
"It was a crime against humanity," said Burjanadze, a former parliament speaker and one of the leaders of the 2003 Rose Revolution which brought Saakashvili to power.
A Russian Foreign Ministry spokesman called the police action a "glaring violation human rights and freedoms" and called for an international investigation, but did not comment on Saakashvili`s allegation of Russian involvement. Human rights watchdogs said police used excessive force.
"Even if the Tbilisi demonstration was unauthorized, nothing can justify the beating of largely peaceful protesters," said Rachel Denber, regional deputy director for Human Rights Watch.
Political analysts said that as long as the opposition was fragmented, there was little threat to Saakashvili, 43, whose term is due to end in 2013.
His domestic opponents accuse him of monopolizing power since the revolution that ousted the post-Soviet old guard in the Caucasus state, where pipelines carry oil from the Caspian Sea to the West, skirting Russia.
Critics accuse him of using his ties with the United States and the European Union to deflect attention from human rights abuses in Georgia.
A wave of protests in 2009 failed to dislodge Saakashvili, and opponents mounted a new challenge this week, calling for his resignation in demonstrations.
