Gurmehar Kaur, the Delhi University student who alleged rape threats over her social media campaign against the student group ABVP, has pulled out of a march today against campus violence. In a series of tweets, the 20-year-old also appealed to others to join the "Save DU" march at the Delhi University campus by students and teachers in huge numbers. "To anyone questioning my courage and bravery. I've shown more than enough," she wrote.
