Russia has levelled strong criticism at the United States and other countries that have recognised the rebel Libyan National Transitional Council.
The foreign minister in Moscow, Sergei Lavrov, accused them of taking sides unnecessarily.
He said: “It means once again that those who declare recognition (of the rebels’ National Transitional Council) stand fully on the side of one political force in a civil war which is ongoing in Libya. It means once again that supporters of such a decision are supporters of a policy of isolation, in this case the isolation of those forces that represent Tripoli.”
Lavrov’s words came as rebels announced a major advance in their campaign against Colonel Gaddafi’s regime, this time around the oil port of Brega.
Latest reports say most government troops have been routed from the city. Rebels have encircled Brega which had marked the eastern limit of Gaddafi’s control.
