KATHY GANNON, ASSOCIATED PRESS - The Israeli military has denied permission for aid groups to move food and medicine to besieged villages in southern Lebanon for two days, the Red Cross said Monday. Without guarantees of safe passage, the Red Cross has been unable to move supplies beyond the port city of Tyre to towns and villages south of the Litani River, where thousands of people are believed trapped, said Richard Huguenin, a spokesman for the International Committee of the Red Cross. . . "It is now a question of the humanitarian consequences of what is looking like a blockade," Huguenin told The Associated Press in Tyre.
