India's women vow to fight on against citizenship law

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.
