TUNIS - Libya's Foreign Minister Moussa Koussa flew on Wednesday afternoon to London from the Tunisian airport of Djerba, the official TAP news agency reported. TAP did not say what initially brought Koussa to Tunisia. It had reported on Monday that he had crossed over into Tunisia from Libya. Koussa is one of Muammar Gaddafi's key officials and the architect of a dramatic shift in Libya's foreign policy that brought the country back to the international community after years of sanctions.
