Every night, 75-year-old Noornissa braves the freezing cold to help block one of the main roads into the capital of India, in a protest that is at the forefront of a rising challenge to Prime Minister Narendra Modi.
For nearly four weeks, Noornissa and more than 200 other women have sat and slept across the four-lane road between Delhi and the satellite city Noida, gaining nationwide attention as
protests erupted across
India over a controversial citizenship law that critics say is anti-Muslim.
Men stand guard as the women, from the mainly Muslim area of Shaheen Bagh, sing the US civil rights anthem "We Shall Overcome" and chant against the Citizenship Amendment Act, passed last month by Modi's Hindu nationalist government.
