NEW DELHI: The Indian government on Monday imposed National Security Act (NSA) for three months as All India Muslim Personal Law Board (AIMPLB) has announced to hold countrywide strike against Citizenship Amendment Act (CAA). Under the act, New Delhi police will have authority to detain anyone without any reason for one year. Nationwide protests are continued against citizenship law passed in December that bars Muslims from a measure granting nationality to minorities from three neighbouring Islamic-majority countries. Hundreds of thousands of people have taken to the streets across the country, and more than 25 people have been killed. Critics say the legislation goes against India’s secular constitution, but Modi says the new law is intended to help “persecuted” minorities.
