More than 100 people were injured in India's capital city on Sunday (December 15) the fifth-straight day of violent protests against a new law.
The act offers a path to citizenship for certain persecuted religious minorities, but not Muslims.
That's sparked criticism of Prime Minister Narendra Modi's government, with some saying the law erodes India's secular foundations.
Thousands gathered near a historic Muslim University in New Delhi, demanding the law scrapped.
Police said protesters burned vehicles, then fled into the university and pelted them with stones.
Officers then entered the campus, firing tear gas.
.Witnesses say students took shelter inside the library before police made them march out.

Since the citizenship act was signed last week, Modi has dug in, telling a rally on Sunday (December 15) that the decision was "1000 percent correct." Meanwhile, protests are still spreading, with more planned for Monday.
