onlineredaktion - A senior Libyan official says he is resigning his post, the second high-profile defection from Muammar Gaddafi's regime in as many days.

Ali Abdel-Salam al-Treki is a former foreign minister and had been named to represent Libya at the UN after a wave of defections early in the uprising. But he says in a statement posted Thursday on several opposition websites that he's decided to resign that post. The announcement comes a day after ex-Libyan Foreign Minister Moussa Koussa flew to England and told the British government he was resigning as well.
