MEXICO CITY, Nov 11 (Reuters) - Bolivia's former President Evo Morales has boarded a plane to Mexico, where he has been granted asylum, Mexico's top diplomat said on Monday night, as unrest shook the South American nation.

The Mexican government's support has helped cement its emerging role as a bastion of diplomatic support for left-wing leaders in Latin America.

"Evo Morales is now on the Mexican government's plane sent to ensure his safe journey to our country," Foreign Minister Marcelo Ebrard wrote on Twitter.

He had said the life of Bolivia's first indigenous president was in danger and the decision to grant him asylum was in Mexico's long tradition of sheltering exiles.

Morales' government collapsed on Sunday after ruling party allies quit and the army urged him to step down in the wake of a disputed election, adding to a sense of crisis in Latin America, which has been hit by weeks of protests and unrest.

Looting and roadblocks convulsed Bolivia after Morales stepped down. He said "violent groups" attacked his house.

"His life and integrity are at risk," Ebrard had told reporters earlier. "We will immediately proceed to inform Bolivia's foreign ministry that under international law, it should offer safe conduct."

Mexico would inform the Organization of American States, and the United Nations, he added. The Washington-based OAS delivered a report on Sunday citing serious irregularities during Bolivia's October vote.

Mexico's plane refueled in Lima before picking up Morales in Bolivia, and Argentina's President-elect Alberto Fernandez praised Peruvian President Martin Vizcarra's cooperation.

"He acted diplomatically to try to facilitate the arrival of the plane for Evo," Fernandez said at an event in Buenos Aires.

The departure of Morales, one of a wave of leftists who dominated Latin America's politics at the start of the century, comes amid a widespread rejection of incumbent leaders from either side of the political divide in the region, from Mexico to Brazil and Argentina.

Mexico elected its first left-leaning government in decades last year, moving closer to like-minded governments and distancing itself from diplomatic initiatives aimed at pushing socialist President Nicolas Maduro from power in Venezuela.

Argentina last month elected left-leaning Fernandez, as voters rejected economic policies that were aimed at stabilizing the economy but which deepened poverty and inflation.

The resignation of Morales, who governed for 14 years, followed protests in Ecuador and Chile that forced their governments to step back from policies raising fuel and transport prices.

Ebrard said earlier on Monday his government viewed Sunday's events in Bolivia as a "coup" because the military broke with the constitutional order by pressing Morales to resign.

Mexican President Andres Manuel Lopez Obrador praised Morales, saying he chose to resign rather than put the lives of Bolivia's citizens at risk. (Reporting by Mexico City Newsroom; Editing by Frank Jack Daniel, Tom Brown and Sandra Maler)
