The deputy head of Libya's ruling National Transitional Council (NTC) said on Sunday he was resigning after a series of protests against the new government which the country's leader warned could drag Libya into a "bottomless pit." Late on Saturday, a crowd demanding the government's resignation smashed windows and forced their way into the NTC's local headquarters in Benghazi, in the most serious show of anger at the new authorities since Muammar Gaddafi was ousted. The NTC has the support of the Western powers who helped force out Gaddafi in a nine-month conflict, but it is unelected, has been slow to restore basic public services, and some Libyans say too many of its members are tarnished by ties to Gaddafi. Abdel Hafiz Ghoga, vice-president of the NTC and one of the council's highest-profile members, was the target of some of the protesters' criticism. He said he was quitting to try to limit the damage to the council. "My resignation is for the benefit of the nation and is required at this stage," Ghoga told Al Jazeera television.
