Gaddafi's tanks reach center of Misrata, several killed by gunfire

Forces loyal to Libyan leader Muammar Gaddafi have entered the center of the rebel-held city of Misrata with tanks, and several people have been killed by gunfire, residents said on Sunday. "Two people were killed so far today by snipers. They (snipers) are still on the rooftops. They are backed with four tanks, which have been patrolling the town. It's getting very difficult for people to come out," one resident, called Sami, told Reuters by telephone. "There are also boats encircling the port and preventing aid from reaching the town."
