Libyan protesters stand on the rooftop of a burned police station, during a demonstration against their Libyan Leader Moammar Gadhafi, in Tobruk, Libya, Wednesday Feb. 23, 2011. Heavy gunfire broke out in Tripoli as forces loyal to Gadhafi tightened their grip on the Libyan capital while anti-government protesters claimed control of many cities elsewhere and top government officials and diplomats turn against the longtime leader.
