• "I appeal to my sisters and brothers of Delhi to maintain peace and brotherhood at all times. It is important... calm and normalcy is restored at the earliest," Modi tweeted on Wednesday.

This week's battles between Hindus and Muslims have seen mobs armed with swords, guns and acid raze parts of a northeastern district of the Indian capital.

The clashes, which also left more than 200 injured, were triggered by protests against a citizenship law seen by many critics as anti-Muslim and part of Modi's Hindu nationalist agenda.

They exploded into brutal violence on Monday and Tuesday, with residents forced to flee their homes after seeing dwellings destroyed, a mosque attacked and a tyre market and two schools set ablaze.

"I appeal to my sisters and brothers of Delhi to maintain peace and brotherhood at all times. It is important... calm and normalcy is restored at the earliest," Modi tweeted on Wednesday.
