Over 250 people went missing in the massive crowd at the Maha Kumbh Mela's opening day. The Uttar Pradesh government's crowd-control measures, including 'Bhula-Bhatka' camps and announcements, helped reunite most. Despite these efforts, some pilgrims, like Sujata Jha and Omwati, remained separated from their families hours after the event. The Mela expects 40-45 crore attendees and concludes on February 26th.
