Singapore/New Delhi: A Singapore Airlines flight from Mumbai to Singapore with 263 passengers on board Tuesday received a bomb threat, prompting Singapore Air Force to send two F-16s to escort the aircraft.

The flight landed safely at Singapore's Changi International Airport on Tuesday around 8 am (local time), the airline added.

"Singapore Airlines confirms there was a bomb threat concerning SQ423 operating from Mumbai to Singapore. The aircraft arrived in Singapore on March 26, 2019, at about 0800hrs (local time).

"There were 263 passengers on board. We are assisting the authorities with their investigations and regret that we are unable to provide further details," a statement issued by the airline said.

The Republic of Singapore Air Force said two F-16C/Ds escorted the SIA aeroplane.

The RSAF said in a Facebook post that two F-16C/Ds were scrambled to intercept the SIA flight.

"Our fighters escorted the airliner till it landed safely at Changi Airport," it said.

All passengers, except for a woman and a child, disembarked safely and had to undergo screening.
