Libyan rebels entered central Tripoli Sunday in a final move to end Muammar Gaddafi's four-decade rule. The militants took over the symbolic Green Square, renaming it "Martyr's Square" for those who have given their lives, and took control of key roads and airports. Sky News showed boisterous crowds cheering in the streets and many waving the red, black, and green flag of the anti-regime forces, while shouting "Allahu Akbar!" (God is greatest!) People also burned posters of Gaddafi and the green flag of the regime they have nearly overturned. According to Libyan government spokesperson Moussa Ibrahim, who insists the regime is still strong, 1,300 people died today in the battle for the capital.
