At least five people died after being shot in clashes between coca farmers and security forces in Bolivia on Friday, local media reported.
A further 34 people were injured and more than 100 were arrested, according to Nelson Cox, the ombudsman of the city of Cochabamba, newspaper El Deber wrote.
The farmers were trying to march through Cochabamba to La Paz to support ousted president Evo Morales, who is in exile in Mexico.
Morales comes from a family of coca farmers.
The police and the military blocked the way of the protesters on a bridge in Sacaba, an eastern suburb of Cochabamba. Jaime Zurita, the police chief in Cochabamba, said the farmers attacked security forces with guns.
 The latest violent clashes come as the country's new interim government and lawmakers from Morales' party are preparing to work together to stage fresh elections and to restore peace following nearly a month of protests.
 Interim President Jeanine Anez's government and the Movement for Socialism (MAS) have held talks sponsored by the country's Bishops' Conference, the European Union and Spain, the daily Pagina Siete reported on Friday. UN Secretary General Antonio Guterres has also sent an envoy to Bolivia.
 Morales, meanwhile, called for "a national dialogue which guarantees the return of our beloved Bolivia on the road to democratically restoring peace," in a post published on Twitter. Morales resigned on Sunday and went into exile in Mexico two days later after the Organization of American States (OAS) reported irregularities in the October 20 elections in which the leftist president claimed an outright victory against his centre-right challenger Carlos Mesa.
Morales has rejected Anez's presidency and maintains that he remains in power, because Congress has not officially accepted his resignation. He told the Mexican daily El Universal on Friday that he was hoping to return to complete his mandate, which expires on January 22, and to organize elections in which he would no longer be a candidate.
Meanwhile, the interim government on Friday made moves that indicated it was willing to cut ties with its Latin American neighbours. All Venezuelan diplomats have been ordered to leave the country because of their alleged interference with domestic matters, Bolivia's interim foreign minister, Karen Longaric, announced.
The move marks a radical break with the policies of Morales, who was one of few remaining backers of Venezuela's Nicolas Maduro. Bolivia's interim government has recognized opposition leader Juan Guaido as Venezuela's interim president. Longaric also said Bolivia plans to leave the ALBA-TCP alliance - an intergovernmental organization founded by Cuba and Venezuela - and is considering leaving the UNASUR Union of South American Nations.
Bolivian ambassadors appointed by Morales will also be relieved of their duties - with the exception of envoys to the Vatican and Peru, she said. Longaric said there was evidence that Venezuelans took part in violent protests against the interim government, and that nine Venezuelans arrested possessed high-calibre weapons.
Cuba's foreign ministry also said it would withdraw medical staff after four members of a Cuban medical team were arrested over alleged participation in pro-Morales protests. The ministry denied that they had financed and organized demonstrations and said they had "strictly" carried out only humanitarian work.
 Nicaragua's leftist President Daniel Ortega earlier accused US "imperialists" of having staged "a coup" in Bolivia and said such action could encourage people in Latin America to "seek arms to take power" in revolutions rather than through elections.
