Bolivia’s political crisis turned deadly after security forces opened fire on supporters of Evo Morales in a central town, killing at least five people, injuring dozens and threatening the interim government’s efforts to restore stability following the resignation of the former president in an election dispute.

Bolivian armed forces have declared support for the opposition senator Jeanine Anez, who assumed presidential powers following the resignation of former leader Evo Morales, and announced their readiness to cooperate with her, Armed Forces Commander Williams Kaliman said on Wednesday.

Bolivian President Evo Morales resigned shortly after the military urged him to do so. Two officials next in line to take over the government also stepped down following weeks of protests.
