|Leaders to meet on Bolivia crisis|
South American leaders are set to gather in Chile on Monday to come up with a plan to prevent Bolivia from breaking apart.
The emergency meeting comes as Evo Morales, Bolivia's president, struggled on Sunday to re-impose order in the country as the toll from violence between opponents and supporters of the government continued to rise.
Al Jazeera's Mariana Sanchez, reporting from Caracas, said the situation was tense and the economic stakes high in Bolivia.
The South American leaders were keen on a way out of the crisis - in part so that Bolivian gas supplies to the region would not be disrupted - but Morales and his opponents had to compromise and offer up some concessions, our correspondent said.
Talks within the country were already under way in La Paz late on Sunday between the country's vice-president and Mario Cossio, the governor of Tarija province representing governors of resource-rich provinces who are against Morales' plans to redistribute wealth to the country's poor indigenous people.
The toll from clashes in Pando province – where Morales declared martial law on Friday – had risen to at least 30, Alfredo Rada, the interior minister said on Sunday, as the authorities accused protesters of setting fire to a town hall and blocking highways in opposition-controlled provinces, impeding fuel and food distribution.
Officials said the toll was expected to rise as more bodies continued to be found in the hills and the river.
Ivan Canelas, a presidential spokesman, said without providing details that opposition-led highway blockades continued on Sunday and that "an armed group" had set fire to the town hall in Filadelfia, a municipality near Cobija.
"There are people who want to continue sowing pain across the region," he said.
The La Paz newspaper La Razon quoted the country's highways chief as saying blockades had halted transit on major roads in the opposition-governed eastern provinces of Tarija, Beni and Santa Cruz.
US rejects accusations
Meanwhile, the US ambassador to Bolivia is on his way out of the country.
Morales and Hugo Chavez, Venezuela's president and staunch Morales ally, ordered the US ambassadors expelled from their countries last week.
But Goldberg denied the charge and called the decision to expel him a big mistake on Sunday in his first public comments on the matter.
"I would like to say that all the accusations made against me, against the embassy and against my nation are completely false and unjustified," he told reporters in La Paz as he prepared to leave.
The gravest challenge to Morales' nearly three years as Bolivia's first indigenous president stems from his struggle with the four eastern lowland provinces where the country's natural gas riches are concentrated and where his government has in effect lost control.
The provinces are seeking greater autonomy from Morales' leftist government and are insisting he cancel a December 7 referendum on a new constitution that would help him centralise power, run for a second consecutive term and transfer fallow terrain to landless peasants.
