The national capital witnessed protest demonstrations by political parties, students' bodies, and civil society groups over the contentious Citizenship (Amendment) Bill on Tuesday.

The Northeast Students' Union is staging a protest against the bill at Jantar Mantar which was joined by people from various walks of life and across organizations.

The CPI(M)'s Delhi state committee members also held a protest at the same venue against the contentious bill, which was passed in the Lok Sabha on Monday. Communist Party of India (Marxist) MPs had earlier held a protest near the Gandhi statue on the Parliament premises.

Members of the Left party were seen carrying banners, saying "CAB waapis lo" (withdraw the CAB) and "Dharm aadharit CAB nahi chalega" (won't accept a CAB based on religion).

Prakash Karat of the CPI(M) while quoted by news agency PTI said, "The Lok Sabha passed the Citizenship Amendment Bill on Monday night. This law is against our Constitution. This law will be passed in Parliament, despite opposition. For the first time, religion has become the base for citizenship."

Another protest, organized by various civil society groups, is scheduled to be held in the evening against the Citizenship Bill as well as the National Register of Citizens (NRC).
