La Paz - The government and opposition agreed to hold a nationwide referendum Sunday on the new draft constitution proposed by the president, after he agreed to term limits, a senior official said.

Rural Development Minister Carlos Romero said on Monday the agreement moves up the next general election by one year, to January 2009, which President Evo Morales would contest for his second and final term.

La Paz  - Negotiations broke down in Bolivia when regional governors in rebellion against the federal government refused to sign an agreement with President Evo Morales' administration, a senior official said.

Rural Development Minister Carlos Romero insisted Sunday night that the two sides made significant advances on the issue of autonomy during 10 hours of talks in the city of Cochabamba.

"They can't say that there wasn't any agreement," Romero said. "If they're trying to say there was no consensus, then they are just playing politics, and we're not interested in that."

But one of the governors said no consensus had been reached.

La Paz - Bolivia's government, led by leftist President Evo Morales, and the conservative opposition adjourned talks until Monday without breakthroughs on key issues in their dispute over autonomy and tax revenues that has led to deadly violence.

Working groups for both sides have been unable to agree on a formula on dividing up tax income from oil and gas between the federal government and states, the opposition's Mario Cossio, governor of the breakaway state of Tarija, said Thursday.

La Paz - Bolivia's leftist President Evo Morales and opposition governors rebelling against his reform plans agreed on Tuesday to start talks to end the violence which threw the country into a crisis.

Talks on the roadmap went ahead despite the arrest of Leopoldo Fernandez, governor of opposition-controlled Pando region. Morales accuses him of having allegedly orchestrated a massacre among his peasant supporters on Thursday, which left at least 15 people dead.

Washington - President George W Bush on Tuesday added Bolivia to a drugs blacklist after concluding that the South American country has failed to cooperate in stemming production and trafficking of illegal narcotics.

Bolivia joins Venezuela and Myanmar - also known as Burma - as failing to meet international obligations to curb drug trafficking, Bush said in a statement released by the White House.

"I hereby designate Bolivia, Burma, and Venezuela as countries that have failed demonstrably during the previous 12 months to adhere to their obligations under international counter-narcotics agreements," Bush said.

Santiago - Bolivian President Evo Morales on Monday in Santiago de Chile alleged that governors of restive regions attempted to topple his government.

He arrived Monday in the Chilean capital to attend a summit of South American presidents, who were expected to discuss the Bolivian crisis.

Morales said that the attempted coup d'etat included "occupation of institutions, looting and robbery from state institutions, attempts to attack the national police and the armed forces, and terrorist actions."
