The British Foreign Secretary William Hague is calling on more countries to contribute to the international coalition that has been carrying out air strikes on Libya. He is co-chairing a meeting in Qatar of the Contact Group of Nations that oppose Col. Gaddafi. Speaking before hand, he said there was a scope for broader involvement. Mr. Hague said diplomacy and sanctions would be used to increase the pressure on Col. Gaddafi to go. Italy has suggested arming the Libyan rebels to help them defy attacks by pro-Gaddafi forces. But Belgium said such a move would not be covered by the United Nations resolution under which the International military action is being carried out.While, U.N. Secretary-General Ban Ki-moon has said that up to 36 lakh people in Libya may need humanitarian assistance as rebels continue their fight against Libyan leader Muammar Gaddafi. Speaking at a meeting of foreign ministers on the future of Libya being held in Doha, Qatar UN secretary general emphasised the need for mobilisation of all means including military. Ban ki moon added that he was in consultation with U.N. agencies and funds for possible contingencies. Foreign diplomats of various countries met in Qatar's capital Doha behind closed door to seek a political exit to the crisis in Libya, after an African Union-initiated peace plan was denied by the Libyan rebels. British foreign secretary William Hague said participants would continue to maintain pressure on Libyan leader Muammar Gaddafi to step down. NATO Secretary General Anders Fogh Rasmussen, as well as envoys from the United States, Arab countries and international organizations participated in the conference.
