The death toll in the worst religious violence to hit India's capital in decades has risen to at least 25, according to a health official.

The violence was triggered after Muslims protesting against a discriminatory citizenship law were attacked.

Over 200 people have been injured during four days of violence in Muslim-populated areas of northeast Delhi, with police accused of looking the other way as a mob on Sunday went on the rampage, killing people and damaging properties, including mosques.

What sparked the violence? The violence was triggered after weeks-long peaceful sit-ins in New Delhi against a new citizenship law were attacked by Hindu nationalist mobs.

Muslims, India's largest minority, say the Citizenship Amendment Act (CAA) passed last December discriminates against them and goes against the country's secular ethos.

Parts of the capital descended into violence on Sunday after a ruling Bharatiya Janata Party (BJP) leader warned Muslims against continuing with sit-ins.

Over the next days, northeast Delhi's Karawal Nagar, Seelampur, Maujpur, Bhajanpura, Vijay Park, Jafrabad, Chandbagh, Mustafabad and Yamuna Vihar witnessed pitched battles between Hindus and Muslims.

India's Hindu nationalist Prime Minister Narendra Modi, who hosted US President Donald Trump as the violence continued, has been criticised for not acting on time.

On Tuesday night, civil society members carried out a solidarity march against the violence.

Day after the mayhem

On Wednesday morning, AFP saw people cleaning out the blackened and trashed interior of a mosque in the Ashok Nagar area burned out during the violence.

A video circulated on social media and verified by AFP showed men ripping off the mosque's loudspeaker on top of the mosque's minaret and placing a Hindu religious flag and an Indian flag.

The new citizenship law has raised worries abroad that Modi wants to remould secular India into a Hindu nation while marginalising the country's 200 million Muslims, a claim he denies.
