Tensions rise between US and Russia
Tensions are rising between the United States and Russia, as Russian troops remain in Georgia.
The US has demanded that Russia withdraw its tanks and soldiers immediately, but as yet there has been no response from Moscow.
This is despite a ceasefire agreement which Russia signed on Tuesday, and Georgia agreed to yesterday.
The violence erupted more than a week ago, when Georgia launched an assault to retake the breakaway province of South Ossetia, provoking a huge counter-offensive from Moscow.
