The Congress and its allies are spreading lies that Muslims will be sent to detention centres, Prime Minister Narendra Modi said today, attacking his opponents amid countrywide protests over the new citizenship law and the National Register of Citizens or NRC. "Congress and its allies - some Urban Naxals - are spreading rumors that all Muslims will be sent to detention center. At least value your education... at least read once about the Citizenship Amendment Act. It's a lie and is dividing the nation," PM Modi said at a mega rally at Ramlila Maidan where he launched the BJP's poll campaign for the assembly elections in Delhi next year.
