A Ukrainian parliamentary team arrived in South Ossetia Monday to investigate reports that Kiev sold weapons to neighbouring Georgia before its summer conflict with Russia.
"We have questions about who organised the delivery" of arms to Georgia ahead of its military offensive on August 7, Interfax agency quoted Valery Konovalyuk, the head of a parliamentary investigation commission, as saying.
Konovalyuk is a member of Ukraine's pro-Russian opposition Party of Regions, which supports the independence of the breakaway provinces of South Ossetia and Abkhazia.
The issue of whether Kiev sold weapons to Tbilisi during the summer conflict has become a major issue in Ukraine, ahead of the country's parliamentary elections scheduled for next month.
Ukraine, which is one of the world's 10 biggest weapons exporters, strongly denies the accusation, made by Russian Prime Minister Vladimir Putin last month.
Its President Viktor Yushchenko, who like his Georgian counterpart rose to power following pro-west revolutions, openly supported Tbilisi in its summer conflict with Moscow.
