Besides Sonam Wangchuk, who are the other 3 people who have been fasting for 21 days

Three student activists persist with their hunger strike at Jantar Mantar. Sonam Wangchuk was moved to Safdarjung Hospital on his twenty-first day of fasting. Organizers confirmed the protest and a planned march to Parliament will proceed. Abhijeet Dipke also began a hunger strike after Wangchuk's removal from the site. Wangchuk appealed for the July 20 Parliament march to be a success.
