Indian police baton-charged protesters Sunday to stop them reaching Prime Minister Narendra Modi\u2019s cavalcade as nationwide protests against a bitterly disputed citizenship law entered a second month.\r\nTens of thousands staged protests through the night in the eastern city of Kolkata to denounce Modi\u2019s weekend visit to the capital of West Bengal state, whose local rulers have strongly opposed the legislation.\r\nPolice said they were forced to act after protesters tried to storm past barricades to stop Modi\u2019s vehicle outside a stadium, where the leader again defended the law and insisted the demonstrators were \u201cmisguided\u201d.\r\nNearly 2,000 protesters gathered outside chanting \u201cFascist Modi, Go Back\u201d before the showdown between demonstrators and police. More than 100 protesters were detained, a police official said.\r\nProtesters have burned effigies of the prime minister during his visit and brandished black flags, which is considered an insulting gesture in Indian society.\r\n\u201cThe government can\u2019t suppress our voice. We are not afraid. We are determined to fight for our rights,\u201d Samit Nandi, one of the protesters, told AFP. \u201cWe will continue our protests until Modi leaves our city.\u201d\r\nWest Bengal has become a political battlefield between Modi\u2019s right-wing Bharatiya Janata Party (BJP) and regional powerhouse Mamata Banerjee, whose Trinamool Congress party leads the state.\r\nBanerjee is among state leaders nationwide who have said they will not implement the Citizenship Amendment Act, which excludes Muslims from a list of ethnic minorities from Pakistan, Afghanistan and Bangladesh who are allowed to seek Indian nationality.\r\nOpponents say the government has created a religious test for citizenship in the secular country.\r\nMany among India\u2019s 200 million Muslims fear the law is a precursor to a national register of citizens that could leave them stateless in the country of 1.3 billion. Many poor Indians do not have documents to prove their nationality.\r\n\u201cCAA is not about taking away citizenship, it is about giving citizenship,\u201d Modi told supporters.\r\nHe has accused political opponents of \u201cmisleading\u201d and \u201cinciting\u201d people against his government.\r\nWidespread demonstrations have rocked the Hindu-majority nation since the law was approved by parliament last month.\r\nAt least 27 people, mostly Muslims, have been killed with police accused of using disproportionate force in several states.
