Libyan rebel forces flooded into the capital of Tripoli last night, battling with loyalists to Col. Moammar Gadhafi. The rebels captured two of Gadhafi's sons, including Seif al-Islam, the assumed heir-apparent. Civilians were celebrating in the streets over what may be the end of Gadhafi's 42 years in power of Libya. In an official White House statment last night, President Obama said "The surest way for the bloodshed to end is simple: Moammar Gadhafi and his regime need to recognize that their rule has come to an end." The BBC's Rupert Wingfield-Hayes reports live from Tripoli, where he is with the rebels, and BBC correspondent Jonathan Head checks in from the rebel stronghold of Misrata, in eastern Libya.
