Pune: Prime Minister Narendra Modi had asked people to take up the task of lighting candles and diyas at 9 pm on Sunday for 9 minutes. But even as most complied with lit candles on their window sill, or diyas in their courtyards, some resorted to bursting crackers.

A minor fire broke out on a stretch of grass near the runway of the Solapur airport in Maharashtra on Sunday night, a fire brigade official said.

According to the official, dry grass around the airport may have been set on fire by someone though the exact cause is still being ascertained.

Prima facie, firecrackers burst by some people while responding to PM Modi's call to switch off lights at 9 pm might have sparked the blaze, the officer added.

There was no casualty or damage to the airport, around 400km from Mumbai, the official said.

Local fire officer Kedar Awte said, The fire broke out around 7 pm and was brought under control soon after.
