India's road-block women vow to fight on against citizenship law

Women in New Delhi brave 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, more than 200 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.
