Morales supporters protest in La Paz
The unrest comes as Bolivia's interim President said on Thursday that Morales would not be welcome to run in new elections.
Jeanine Anez, 52, who took over on Tuesday, is battling to bring calm to a sharply divided Bolivia that has been rocked by protests since the Oct. 20 election, which was won by Morales but marred by widespread allegations of fraud.
Morales, a leftist, resigned on Sunday after an audit found electoral irregularities and the military withdrew its backing and urged him to step down as president to help restore calm.
Morales and his vice president Alvaro Garcia, who also resigned, have been offered asylum by Mexico.
"Evo Morales does not qualify to run for a fourth term," conservative former senator Anez told a news conference on Thursday.
Anez said that it was because of Morales, in power since 2006, defying term limits that "we've had all this convulsion, and because of this that so many Bolivians have been demonstrating in the streets."
