Bolivia's new president has called for national unity, hours after his predecessor was forced out by weeks of violent anti-government protests. The new leader, Carlos Mesa - the former vice president - quickly offered to hold early elections and promised to do more for the indigenous Indian population. In a special session, the Bolivian Congress accepted the dramatic resignation of Gonzalo Sanchez de Lozada - just 14 months into his term. He was brought down after more than a month of protests over plans to export natural gas which have left scores of people dead.
