HUNDREDS of houses in ethnic Georgian villages in South Ossetia were torched in August, after Russian troops took control of the area, according to an analysis of satellite images.
The analysis, by the American Association for the Advancement of Science on behalf of Amnesty International, did not show who was responsible for the damage but Amnesty said it may be evidence of war crimes.
Human rights activists have criticised Russia for ignoring the looting of ethnic Georgian villages by armed South Ossetian militias during and after the war.
Georgia says the looting amounted to "ethnic cleansing". Russia says Georgia`s shelling of the South Ossetian capital Tskhinvali - which sparked the war - amounts to a genocide against the Ossetians. Both deny the other`s claims.
"These images do not lie - the additional destruction shown from August 10 to August 19 must be used to establish who had responsibility for protecting civilians from attacks by militia," said Amnesty`s Ariela Blatter.
"The destruction of civilian infrastructure highlights the need for the international community to undertake an independent investigation of abuses during the conflict, with the complete support of all parties involved."
The war erupted in August when Georgia tried to retake by force South Ossetia, a tiny breakaway region that threw off Georgian rule in a war in the 1990s and is supported by Russia.
Moscow responded on August 7-8 with a counterattack that overwhelmed Georgian forces and deepened fears over the security of the Caucasus as a way to take oil and gas from the Caspian Sea to Europe without going through Russia.
Russia and Georgia have accused each other of targeting civilians during the war, though there was little way to assess the validity of the claims as many ethnic Georgian villages in South Ossetia were off limits to reporters during the war.
