Braving the freezing cold, thousands of people -- mostly women -- have been camping out at a park in Prayagraj for the last three days in a protest against the citizenship law inspired by Delhi's Shaheen Bagh. By 4 pm, the crowd at Mansoor Ali Khan park, located around 200 km from state capital Lucknow, has swelled to around 5000 people. Many listen to speeches made by student organisations from the Left and the Samajwadi Party. Others are busy recording the moment on their cellphones.
