India battles coronavirus in its biggest slum

According to an AFP report, the nearly 1,25,000 people are under a lockdown so strict that drones monitor their moves and alert police if they attempt to leave their homes.

"The biggest challenge is Dharavi itself....10 to 15 people stay in one room. How is it possible to enforce social distancing?" asked city official Kiran Dighavkar.

The Roti Bank Foundation's operations manager Jayandrath Tambe told AFP the non-profit organised 4,500 meals daily for Dharavi's confined residents and was feeding 32,000 people across Mumbai with the help of local hotels.

Social worker Imran Idris Khan turned to YouTube to upload videos explaining relief efforts in Dharavi and used WhatsApp to inform residents about where to find food.

"Many families are still sitting at home or people are stuck in factories without any idea about food-packet distribution drives and therefore going hungry," he told AFP. "This should not be happening."
