Russia moving further into Georgia

TBLISI, Georgia (CNN) - Russian soldiers warned Georgian troops to move out of their way as they intend to advance into Georgia's western region, Georgian Interior Ministry spokesman Shota Utiashvili said Sunday.

The Russian forces plan to move into the city of Zugdidi, which is beyond the border of the breakaway province of Abkhazia, Utiashvili said.

White House Deputy National Security Advisor Jim Jeffrey said the United States was urgently looking into the report, saying that it would be a very serious escalation for Russia to move into Georgia beyond the Abkhazia region.

Jeffrey, speaking to reporters in Beijing Sunday, said Russia's failure to end its "disproportionate" action against Georgia could have a "significant long term impact on U.S.-Russian relations."
