Three protesters were killed during clashes in several parts of the Indian capital, the Press Trust of India news agency reported, and police said one officer died in the violence. An unnamed health official said on Tuesday that another two had died, Reuters reported.
Eleven police were injured as they were hit by rocks trying to separate rival groups, New Delhi police said.
Dozens of supporters of the Communist party of India carried a banner reading “Trump go back”. Anti-Trump street demonstrations also broke out in the cities of Gauhati in the north-east, Kolkata in the east and Hyderabad in the south.
Also in Delhi, police fired tear gas as clashes erupted between hundreds of supporters and opponents of a new citizenship law that provides fast-track naturalization for some foreign-born religious minorities but not Muslims.
Critics say the country is moving toward a religious citizenship test. The protesters blocked a busy road in a north-eastern district of Delhi, replicating similar sit-ins in several parts of India since the law was passed in December.
Police used tear gas as the rival groups hurled rocks at each other in the area on Monday and set some houses, shops, vehicles and a petrol pump on fire. Police closed access to two metro stations in the area.
Delhi’s highest elected official, Arvind Kejriwal, tweeted that the violence was “very distressing”.
The New Delhi television news channel said authorities deployed paramilitary forces to defuse the situation.
