Thousands chant long live Assam during unrest sparked by MPs approval of a law that excludes Muslims
The death toll from bloody clashes sparked by contentious citizenship law has risen to six as protesters in north-east India vowed to continue demonstrations.
Tensions remained high at the epicentre of the unrest in Assam states biggest city, Guwahati, with troops patrolling the streets on Sunday.
In Assam, four people died after being shot by police, while another was killed when a shop he was sleeping in was set on fire and a sixth after he was beaten up during a protest, officials said.
Some 5,000 people took part in a fresh demonstration on Sunday in Guwahati, with hundreds of police watching as they sang, chanted and carried banners with the words long live Assam.
The legislation, passed by parliament on Wednesday, allows Delhi to grant citizenship to millions of illegal immigrants who entered India from three neighbouring countries on or before 31 December 2014 but not if they are Muslim.
Besides stoking concern among Muslims, the proposed changes have also led to protests by residents unhappy about an influx of Hindus from Bangladesh, who stand to gain citizenship.
Assam will continue to protest. India is a democracy and the government has to listen to us, said Karan Mili, a colleague of one of the victims, 25-year-old Iswor Nayak, who died on Sunday.
We dont want violence but protests will continue … Assamese will not stop until government revokes the law, another demonstrator, Pratima Sharma, said.
Officials said oil and gas production in the state were hit by the curfew, although the restrictions were eased during the day on Sunday with some shops opening.
In West Bengal state, where protests stretched into a third day, chief minister Mamata Banerjee who has spoken out against the national governments push for the law suspended internet service in several districts.
