Is this finally Gaddafi’s last stand? The National Transitional Council, the former Libyan rebels, fought their way into Sirte, one of the last areas of the country still loyal to ousted leader Col. Muammar Gaddafi. A NTC spokesman said fighters had breached Sirte’s defenses, but were still meeting heavy resistance. Gaddafi’s spokesman, Moussa Ibrahim, said there are “thousands of volunteers” willing to “liberate Libya” from the former rebels. Meanwhile, British Prime Minister David Cameron and French President Nicolas Sarkozy visited Libya’s first liberated city, Benghazi, on Thursday, as Cameron pledged further aid, saying they would continue to give aid until Gaddafi is found. On Friday, the NTC sent a delegation to neighboring Niger in an effort to recover gold and cash believed to be stolen from Libya by fleeing Gaddafi loyalists.
