GENEVA, March 20 - Russia may be preparing a further military incursion to Ukrainian territory, Ukraine's ambassador to the United Nations in Geneva, Yuriy Klymenko, told U.N. diplomats at a briefing on the human rights situation in Ukraine on Thursday.

"There are indications that Russia is on its way to unleash a full blown military intervention in Ukraine's east and south," Klymenko said.

His statement was widely supported by other ambassadors, but challenged by a Russian diplomat, who read a prepared statement justifying Russia's actions so far.
