UPDATE 1-Saakashvili says Russia wants to replace his gov't

(Combines Saakashvili comments, adds details)

MOSCOW, Aug 11 (Reuters) - Georgian President Mikheil Saakashvili said on Monday that Russia wanted to replace his government and to control energy routes through the Caucasus.

Saakashvili, speaking to reporters on a conference call, said 90 percent of Georgian casualties in the conflict with Russia over the breakaway region of South Ossetia were civilian. Georgia has previously said 80 percent of casualties were military.

Russia "wants to replace the government in Tbilisi", Saakashvili said. "It wasn't for them about South Ossetia ... it's about controlling energy routes."

A major pipeline through Georgia carries oil from Asia to the West.

The Georgian president said Russian tanks were repelled five km (3 miles) from the Georgian city of Gori, which is about 50 km (30 miles) from the South Ossetian capital Tshkinvali.

"They were five kilometres from Gori. They were repelled and now they are 20 kilometres away," he said, before the conference call was abruptly cut short.

A Reuters correspondent said he had not seen any Russian tanks advancing on Gori.

"Our losses are mainly civilian. Ninety percent of our casualties are civilian," Saakashvili said. (Reporting by Conor Sweeney; Writing by Robin Paxton; Editing by Giles Elgood)
