The deputy head of Libya's National Transitional Council says he is resigning his post a day after anti-government protesters stormed the ruling body's offices in the eastern city of Benghazi.

Abdel Hafiz Ghoga announced his resignation in an interview with Al-Jazeera television Sunday. A day earlier, rioters threw stones and hand grenades at the NTC complex in Benghazi, entering the site while senior officials were inside. It was the most serious display of public anger toward the NTC since Gadhafi's ouster.

The protesters accused the NTC of neglecting wounded rebels who helped to overthrow Libyan dictator Moammar Gadhafi last year. They also denounced the presence of former Gadhafi loyalists in the NTC, calling them “opportunists.”

Ghoga was a belated defector to the Libyan rebels from Gadhafi's government. Some of Saturday's protesters had chanted slogans against him.

NTC officials led by the body's chief Mustafa Abdel Jalil met again in Benghazi on Sunday. Ahead of the meeting, he said the NTC would adopt a draft law for national assembly elections that it has promised to hold in June.

Benghazi was the birthplace of the revolt against Gadhafi's 42-year autocratic rule of Libya.
