Protests over a controversial new law on migrants are raging across several Indian cities, prompting police to clash with demonstrators.

The new law entitles non-Muslim migrants from three Muslim-majority countries to citizenship if they are facing religious persecution.

Police used tear gas and detained protesters in the capital Delhi as buses were torched and roads blocked.

Protests have raged across northern and eastern India since the law was passed.

Internet services have been shut down in several cities where protests are taking place. Universities across the country have resumed demonstrations on Monday.

Some critics say the law is anti-Muslim, while others - especially in border regions - fear large-scale migration.

Six people have been killed in the five days of unrest.

Over the weekend, demonstrators in West Bengal blocked key national highways while in Assam, the state government briefly lifted a curfew to allow people to buy essential goods.
