Libya's rebels want Brega's oil resources to finance their troops. Meanwhile, the US increasingly sees Yemen's Saleh as a destabilizing factor.
Pro-government and rebel forces are still locked in a standoff around Brega, where both sides have been engaged in fighting since the middle of last week. Rebels took part of the city Wednesday, but have been the target of heavy fire from Col. Muammar Qaddafi's troops since then.
The rebel troops hope to retake Brega in order to be in control of the city's oil resources, which would provide a much-needed financial boost that could translate to more weapons, The Wall Street Journal reported.
Colonel Qaddafi's son, Saif al-Islam Qaddafi, told the BBC that Foreign Minister Moussa Koussa had not actually defected from Libya. He said that Mr. Koussa was in Britain for health reasons and had been pressured into denouncing the Libyan government in order to secure immunity.
