Bolivian President Carlos Mesa has submitted his resignation to Congress amid angry protests demanding nationalization of the country's oil and gas industry.
Mr. Mesa made the announcement in a nationally televised address late Monday.
Congress must still vote to accept the resignation. President Mesa had also submitted his resignation earlier this year, but it was rejected by lawmakers.
Meanwhile, tens of thousands of protesters marched in Bolivia's largest city, La Paz Monday in the largest demonstration yet in weeks of civil unrest.
Indian and labor groups have staged the protests and set up roadblocks to demand the redistribution of oil and gas profits to the country's impoverished majority.
