At least three persons died on Thursday evening after police opened fire on the demonstrators protesting against the Citizenship (Amendment) Bill in Assam's Guwahati.
The identities of the deceased are yet to be ascertained.
An officer told PTI that the protesters hurled stones and bricks at the policemen and when attempts to pacify them did not deter the mob, the security personnel opened fire at them.
The state has been on edge as thousands of angry protesters came out on streets defying curfew, thumbing their nose at Army contingents staging flag marches, and clashing with police across cities.
Five columns of the Army have been requistioned and deployed in Assam.
Meanwhile, Chief Minister Sarbananda Sonowal in a video appeal to the people assured that the state's traditional culture, language, political and land rights would be protected by implementing Clause 6 of the Assam Accord.
The Centre has categorically stated that the recommendations of Clause 6 Committee will be fully implemented within a timeframe, the chief minister said.
Governor Jagdish Mukhi also appealed to the people to maintain peace in the state. "If the student community has any issues against the government they have every right to agitate but they should do it in a democratic and peaceful manner, without taking the law in their hands," he said.
The Citizenship Bill has been cleared in both Lok Sabha and Rajya Sabha, and is awaiting Presidential assent.
According to the proposed legislation, members of Hindu, Sikh, Buddhist, Jain, Parsi and Christian communities, who have come from Pakistan, Bangladesh and Afghanistan, till December 31, 2014 facing religious persecution there, will not be treated as illegal immigrants but given Indian citizenship.
