Police have clashed with demonstrators in parts of the Indian capital, Delhi during protests over a controversial new law on migrants.

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 truncheons against protesters as buses were torched and roads were blocked.

Protests have raged across north and east India since the law was passed.

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

This 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.

The UK, US and Canada have issued travel warnings for people visiting India's north-east, telling their citizens to "exercise caution" if travelling to the region.
