¡¡   LIMA, June 8 (Xinhuanet) -- Bolivian protesters blocked more roads throughout the Andean country on Wednesday, hinting at the possibility that the National Congress could have to suspend a special meeting on President Carlos Mesa's resignation on Thursday, reports reaching here said.

    The police estimated 120 places of the country's road network have been blocked, all but isolating six departments. Peasants and Indians peacefully occupied three oil wells in the north of the eastern department Santa Cruz. Other fields of the province have been occupied since last Friday.

    Reports said Evo Morales, leader of the political party Movement Towards Socialism and Roman Loayza, head of the Peasant-Workers Trade Unions Confederation, as well as chiefs of other organizations have called on peasants and Indians to block the congress meeting in Sucre, southeast of La Paz. The meeting was moved to the city as La Paz was too volatile.

    The Murillo Square in downtown La Paz, where Bolivian legislative and executive branches are located, remains cordoned off by the police and the military to prevent them from being taken over by the demonstrators.

    The protesters' roadblocks have also caused a shortage of basic products and fuel, especially in La Paz and El Alto, the centers of demonstrations over the past four weeks.

    The unrest in Bolivia erupted after the National Congress passed a law on May 17 to levy a 50-percent tax on foreign oil andgas companies operating in the country, which has the second-largest gas reserves in South America after Venezuela.

    The opposition demanded higher taxes on foreign firms and nationalization of the country's lucrative oil and gas industry. They also demanded the resignation of Mesa and a rewriting of the constitution to boost indigenous representation in the congress.

    Late on Monday, Mesa announced his decision to resign after protesters threatened to storm the presidential palace earlier. The leaders of Bolivia's National Congress Tuesday decided to resume the session to discuss Mesa's resignation. Enditem
