NEW DELHI • Five passengers on board an IndiGo airline bus at a Delhi airport were injured after a window on the bus shattered due to the impact of a jet blast, allegedly from a taxiing SpiceJet plane, the Indian media reported yesterday.

The incident took place at the Indira Gandhi International Airport at 4.50pm local time on Friday, the NDTV news website reported.

Jet blast refers to the force of hot air produced by the jet engines of aircraft during or before take-off.

In a statement, the low-cost Indian airline said: "IndiGo Coach number 34 was parked at Bay 17 today at 16:50 hours for boarding of passengers on flight 6E-191 en route Delhi-Mumbai. At the same time, an arriving aircraft of SpiceJet SG-253 took to park at the allocated bay. The jet blast from the aircraft broke the right front window glass of the coach."

The airline said that the five who sustained minor injuries were taken to the airport clinic. The plane later departed.

SpiceJet said it was "too early to say if the incident was caused by jet blast", The International Business Times reported. India's aviation regulator is investigating the case.
