Passengers at an Indian airport were shocked when a hardcore porn movie was played on television screens for 20 minutes.

It happened at New Delhi's Indira Gandhi international airport at midnight when the airport was at its busiest.

Passengers were shocked by the sex scenes accompanied by moans and groans which echoed around the terminal.

Officials turned off the TV screens after complaints from passengers but the porn film was broadcast for 20 minutes.

Airport officials later claimed that a TV channel was broadcasting the film as part of an Aids awareness project.

However, airport sources claimed some employees were watching a blue film and accidentally sent it out on the airport's television sets.
