A group of Muslim women who formed a barricade around a male student being attacked by baton-swinging police have become symbols of the protests currently gripping India.

In a video that has gone viral, the four young women rush to surround the young man as police in riot gear thrash at him with six-foot (two-metre) bamboo sticks known as "lathi".

They then point their fingers at the officers and shout "police go back, go back" during the incident in New Delhi on Sunday.

The protests, which raged for another day on Tuesday, follow the passing by parliament last week of legislation making it easier for people from three neighbouring countries to get Indian citizenship.

Excluded though are Muslims, in what Islamic groups, the opposition and rights groups say is part of Prime Minister Narendra Modi's agenda to remould India as a Hindu nation, something he denies.

Fresh protests rocked India Monday as anger grew over new citizenship legislation slammed as anti-Muslim, with six people dead in the northeast and up to 100 reported injured in New Delhi."I want to make it clear, nobody is scared. Like people in Hong K
Fresh protests rocked India Monday as anger grew over new citizenship legislation slammed as anti-Muslim, with six people dead in the northeast and up to 100 reported injured in New Delhi."I want to make it clear, nobody is scared. Like people in Hong Kong are protesting, in Chile they are protesting, and they are not scared. We are not scared too...We want to dissent against the state. They just can’t get acts and bills on the basis of religion," says one student protester AFPTV / Maude BRULARD

The women from Sunday's incident have since been interviewed by myriad media, while the finger-wagging image is being used for protest posters and a Chennai artist's illustration that has spread widely online.

"We don't have any fear of this government, the police or anyone," one of the women, history student Ayesha Renna, 22, told an Indian television channel.

The clashes on Sunday night, which saw vehicles torched and Delhi security forces storm a university, have sparked anger about alleged police brutality, adding fuel to the protests.

"Students have the right to protest. Violence against peacefully protesting students cannot under any circumstance be justified," rights group Amnesty International said on Monday.

Police spokesman MS Randhawa said four buses, 100 private vehicles and 10 police bikes were damaged, and that officers exercised "maximum restraint, minimum force" despite being "provoked".
