Indian police said Monday they have filed initial charges against six people over a massive explosion during a banned fireworks display that killed more than 100 people and left many more with horrific burns, AFP reports.

Thousands had packed into a Hindu temple in the southern state of Kerala on Saturday night for the show when a stray firework apparently landed on a stockpile of them, triggering a huge blast that tore through concrete buildings.

Three people died of their injuries overnight, taking the death toll from the disaster to 109. Hundreds more are still being treated.
