Violent protests erupted near Jamia Millia Islamia in Delhi and at the Aligarh Muslim University in Uttar Pradesh, while West Bengal plunged deeper into chaos on Sunday during the stir over the new citizenship law with incidents of arson and loot reported from the state and the northeast, acts which Prime Minister Narendra Modi alleged were being instigated by the "Congress and its friends".
An uneasy calm prevailed in Assam, epicentre of the agitation, as curfew was relaxed in Guwahati and Dibrugarh for several hours following improvement in the situation but peaceful protests were held amid calls by the Asom Gana Parishad (AGP) for resignation of its ministers.
The party, which is part of the BJP-led government in Assam, decided it will move the Supreme Court against the amendments made in the Citizenship Act.
In Assam's Guwahati, two more persons succumbed to gunshot wounds suffered in the police firing on Thursday, taking the toll to four. However, protesters claimed that five persons have died in police firing.
In the national capital, protesters torched four public buses and two police vehicles as they clashed with the police in New Friends' Colony near Jamia University during a demonstration against the amended Citizenship Act, leaving six cops and two firemen injured, officials said.
Sources said that at least 31 students were brought to a nearby hospital after the violence and 11 of them were admitted.
Soon after the violence, Jamia Millia Islamia Chief Proctor Waseem Ahmed Khan claimed that the Delhi Police entered the campus forcibly without any permission and beat up staff members and students who were forced to leave the campus.
Condemning the police action, university vice chancellor Najma Akhtar said students who were inside the library which was allegedly surrounded by the police have been taken out and are safe.
Police said they entered the university campus only to control the situation, after protesters indulged in violence.

At a poll rally in Jharkhand's Dumka, PM Modi said, "The Congress and its allies are stoking fire over the Citizenship Act, but people of northeast have rejected violence. Actions of the Congress prove that all decisions taken in Parliament are correct."
"People who are setting fire (to property) can be seen on TV... They can be identified by the clothes they are wearing," he said without elaborating.

AGP leader Kumar Deepak Das said the party would file a petition in the Supreme Court for revocation of the amended Citizenship Act, even as party functionaries urged its top brass to clear their stand on the issue.
Members of the AGP's Guwahati unit also held demonstrations outside party headquarters in Ambari area, demanding resignation of three ministers, including party chief Atul Bora.
Later, at a press conference, Bora said as the legislation has already become an Act, at least the Brahmaputra valley should be excluded and it may be implemented in the Barak valley.
The Barak valley, which has a significant Bengali population, has not seen any major agitation.
AGP leader and Assam minister Keshab Mahanta said the party has not left its "old stand" of opposing the law.
"Though we are a part of the NDA, our stand has not changed. We still do not want this Act to be implemented in Assam and the northeast," he said.
The party's lone MP in Rajya Sabha, Birendra Prasad Baishya, opposed the Bill during discussion, but voted in favour of it following which the party is facing severe criticism.
Students organisations AASU and AJYCP also took out rallies across the state, seeking revocation of the law.
