Filmmaker Mahesh Bhatt on Sunday took a pledge not to support the Citizenship Amendment Act (CAA). He along with Congress leader Sanjay Jha joined a protest meet here. A video is doing the rounds on the Internet in which Bhatt is seen taking the pledge, perhaps a few days back. "We believe Citizenship Amendment Bill is discriminatory and it violates the constitutional values. We don't accept this bill and if it becomes a law we shall boycott its execution. We pledge not to submit any documents if asked to prove our citizenship," he has said in the video. After attending the press meet, Bhatt on Sunday tweeted: We the people of India , having solemnly resolved to constitute India into a SOVEREIGN SOCIALIST SECULAR DEMOCRATIC REPUBLIC.(At Ambedkar's abode. After reading the Preamble of our Constitution)." Several parts of India have been witnessing violent protests ever since the Citizenship (Amendment) Bill was passed in Lok Sabha last week. The situation further escalated after the bill was cleared in Rajya Sabha. The Bill, which has since become an Act, will provide Indian nationality to Hindus, Christians, Sikhs, Parsis, Jains and Buddhists fleeing persecution in Pakistan, Afghanistan and Bangladesh. The issue has caused widespread unprecedented violent protests in the northeast, especially in the states of Assam, Tripura and Meghalaya, with the agitating demonstrators demanding the withdrawal of the CAA claiming that the fresh legislation would jeopardize the demographic situations and life, culture and socio-economic positions to the 45.58 million populations of region. On Sunday afternoon, four buses were burnt in South Delhi as protesters clashed with police.
