At least three people were killed and many injured as government forces in Nicaragua launched an operation to regain control of the city of Masaya. Residents say security forces and militias used disproportionate force to clear barricades on Tuesday. The operation began a day after the collapse of talks between President Daniel Ortega’s government and the opposition. More than 180 people have died over the past two months during anti-government protests. Protesters blame the government and loyalist militias for most of the violence.
