Protests over a new citizenship law based on religion spread to student campuses across India on Monday as critics said Prime Minister Narendra Modi's government was pushing a partisan agenda in conflict with India's founding as a secular republic.

Anger with Modi's Hindu nationalist government was further fueled by allegations of police brutality at Jamia Millia Islamia university on Sunday, when officers entered the campus in New Delhi and fired tear gas to break up a protest. At least 100 people were injured in the clashes there.

There were similar scenes at the Aligarh Muslim University in the northern state of Uttar Pradesh, where police also clashed with protesters on the campus.
