UNITED NATIONS (AFP) - International inspectors have to visit hundreds of suspected weapons stockpiles in Libya amid growing fears that huge numbers of shoulder-fired missiles have been looted, a UN envoy said Wednesday. Ian Martin, head of the UN mission in Libya, also told a Security Council meeting that new previously undeclared sites for storing chemical weapons had been uncovered since the fall of Muammar Gaddafis government. World powers have raised fears that militant groups in neighboring countries have obtained Gaddafis weapons and that the arms could fall into the hands of Al-Qaeda followers.
