Demonstrators opposed to Bolivian President Evo Morales' reform plans have set up roadblocks in parts of the country's energy-rich east on the second day of an anti-government strike.
President Morales condemned the protest Wednesday and threatened to take measures to restore order.
Tuesday, the conservative governors of five low-lying eastern states began the strike to demand greater autonomy for their energy-rich region.
Mr. Morales' critics oppose his plans to redistribute natural gas revenues to the poor, saying they want to keep more of that income from their states.
President Morales recently won an overwhelming victory in a national recall referendum and says the outcome reaffirms his mandate and validates his plans.
Four opposition governors were reaffirmed in the referendum as well.
The president's critics are also concerned about the president's proposals to write a new constitution. They say Mr. Morales leans too far to the political left and is allied too closely with Venezuela's socialist president, Hugo Chavez.
