New Delhi: Prime Minister Narendra Modi on Thursday (December 12) assured the people of Assam that no one could take away their rights, unique identity and beautiful culture, amid protests in parts of the state against the Citizenship (Amendment) Bill, 2019.

"I want to assure my brothers and sisters of Assam that they have nothing to worry after the passing of #CAB. I want to assure them- no one can take away your rights, unique identity and beautiful culture. It will continue to flourish and grow," the Prime Minister tweeted.

"The Central Government and I (PM Modi) are totally committed to constitutionally safeguard the political, linguistic, cultural and land rights of the Assamese people as per the spirit of Clause 6," he said in another tweet.

During the discussions on the CAB, Union home minister Amit Shah had said that Prime Minister Narendra Modi-led government is committed to preserving linguistic and cultural rights as well as the social identity of people in northeastern states.

"In northeastern states, we will try to address the issues raised by them about the law. We repeat our commitment to preserving the language, culture, and social identity rights of northeastern states. There are provisions to preserve these rights. The concern of the northeast will be addressed, we had said this earlier," he said.

Assam's capital city Guwahati and its district Dibrugarh have been placed under indefinite curfew till further orders in the wake of protests after the passage of the Citizenship (Amendment) Bill (CAB) in Rajya Sabha on Wednesday.

The administration has also suspended mobile Internet services for 24 hours from 7 pm on Wednesday in ten districts of the state-Lakhimpur, Tinsukia, Dhemaji, Dibrugarh, Charaideo, Sivasagar, Jorhat, Golaghat, Kamrup (metro) and Kamrup.

An order of the Assam administration warned that violation of the "promulgation" would be punishable under Section 188 IPC and also under the relevant provisions of the Indian Telegraph Act, 1885.

The decision came in the wake of protests in the state against the CAB.

Also, the Indian Army said that two columns of Assam Rifles troops have been deployed in Tripura and the third column in Assam is on standby at the request of the Civil Administration in Tripura and Assam.

The Bill seeks to grant Indian citizenship to refugees from Hindu, Christian, Sikh, Buddhist and Zoroastrian communities fleeing religious persecution from Pakistan, Afghanistan, and Bangladesh and who entered India on or before December 31, 2014.
