New Delhi, India (CNN) At least 15 people have died in violence in India's Uttar Pradesh state since the protests against a controversial new citizenship law erupted last week, police said Saturday. The latest figure raises the overall death toll across the country to 22.

More than 260 police personnel have been injured in the violence and arson in the state, Praveen Kumar, inspector general of Uttar Pradesh Police, said in a news conference.

CNN reported that on Thursday, two others were killed in protests in the city of Mangalore. Last week, five were killed in northeastern Assam state when protests first erupted.

At the center of the unrest is the Citizenship Amendment Act (CAA), which was passed into law last week. The law promises to fast-track citizenship for non-Muslim religious minorities from Pakistan, Bangladesh and Afghanistan who arrived in India before 2015.

People have taken to the streets across India in response to the new rules, which was passed into law last week, despite a ban on public gatherings in various regions now in place.
