Georgia claims that an EU-commissioned report concludes that Russian troops were responsible for ethnic cleansing during last year's war with Georgia.

A Georgian official briefed by a European Union investigator on the report's findings, said Tuesday that the report also concludes that some Russian combat troops crossed into Georgian territory in South Ossetia before the start of hostilities on the night of Aug. 7, 2008.

The official spoke on condition of anonymity because of the sensitivity of the briefing ahead of the report's expected release Wednesday. Both sides want to use the report's findings to bolster their claims about the war.

Georgia has claimed— and Russia has denied— that Georgia launched an offensive to repel Russian forces that had crossed into its territory.
