BBC correspondent Alan Johnston was released early Wednesday, ending the longest ever captivity of a journalist in Gaza. "I am so glad to be free," Johnston told CNN's Ben Wedeman. "It's great to be able to talk to people like you." The ordeal, which began when he was kidnapped March 12 by a group calling itself the Army of Islam, was "a nightmare, and I didn't think it would ever end," Johnston said. Appearing at a press conference with former Palestinian Authority Prime Minister Ismail Haniya, Johnston said his captivity was "like being buried alive, really ... you didn't know when it might end."
