Peruvians protesting the abrupt ouster of president Martin Vizcarra clashed on the streets of Lima on Thursday night with riot police, who fired tear gas to disperse the crowds. The clashes, and other more peaceful protests in the capital and other cities, are piling pressure on a fragmented Congress and the new government of Manuel Merino. Mr Vizcarra, a politically unaffiliated centrist who is popular with voters, was ousted on Monday in an impeachment trial over allegations he received bribes, an accusation he denies.
