The deadliest clashes occurred Friday in the central city of Cochabamba, where nine people were killed in a confrontation between Morales backers and the security forces.

By a narrow margin, voters in Bolivia have rejected a constitutional change that would have allowed leftist Evo Morales, South America's longest-sitting president, to run for a fourth term and potentially extend his rule to 2025.
