PRAYAGRAJ, India — At least 30 people were killed and many more injured in a stampede at the world’s largest religious gathering early Wednesday, police said, as millions of pilgrims rushed to dip in sacred waters during the Maha Kumbh festival in northern India.

Now, in the wake of this incident, five major changes have been introduced to avoid such mishaps. The entire Maha Kumbh fair area has now been declared a No-Vehicle Zone, with all types of vehicles strictly prohibited from entering. This includes the cancelation of VVIP passes that previously allowed vehicle entry.
