veteran Libyan diplomat Ali Treki took the helm of the U.N. General Assembly, calling for stepped up efforts to achieve Mideast peace, close the widening gap between rich and poor, and eliminate nuclear weapons.
In his address Tuesday to the opening of the assembly's 64th session, the former foreign Secretary and U.N. ambassador also called on all 192 member states to take part in the search for solutions to the global economic crisis, to address the roots of terrorism and keep working to reform the United Nations.

Libyan doctors are to be trained by the NHS following an agreement signed by a Cabinet minister last year, it has emerged.
The agreement is the latest in a series of moves to normalise relations between Britain and the north African state, which was an international pariah for years after being blamed for the 1988 bombing of PanAm flight 103 over Lockerbie, which killed 270 people.
But the Department of Health dismissed as "nonsense" suggestions that the agreement had any link with the recent release of Lockerbie bomber Abdelbaset al-Megrahi or trade deals with the oil-rich regime of Colonel Muammar Gaddafi.
