A massive protest has broken out in India's capital Delhi - as anger at a citizenship law spreads across the country. Images from the city's Seelampur area showed stone-throwing crowds facing off against police officers. Police are retaliating with tear gas and batons. Local reports say several protesters and officers have been injured. The protest comes days after clashes between police and protesters in Delhi left at least 50 injured. The new law offers citizenship to non-Muslims from three nearby countries. Seelampur, in the east of the city, has a large Muslim population. Protesters are claiming that the act will marginalise them. There are reports of a police station being set on fire and police have said that buses have been vandalised. Meanwhile, the Supreme Court on Tuesday refused to hear a petition against the police action inside Delhi's Jamia Millia Islamia University, where they allegedly attacked students inside campus premises, including the library and toilets. Chief Justice Sharad Bobde said the top court did not have to intervene since it was "a law and order problem". He also told lawyers to file petitions in trial courts. More protests have broken out, including at Jamia Millia Islamia. A student there told the BBC that hundreds of students had joined demonstrations for the third day in a row. Prime Minister Narendra Modi said the new law was "for those who have faced years of persecution outside and have no place to go except India". But some say the Citizenship Amendment Act (CAA) is discriminatory and part of a "Hindu nationalist" agenda to marginalise India's 200-million Muslim minority. Others - particularly in border states - fear being "overrun" by new arrivals from Afghanistan, Bangladesh and Pakistan.
