A bomb threat on a plane which was about to leave Faro airport in Portugal’s southern region of Algarve for Lisbon was evacuated early on Tuesday, a spokesman for the country’s flag carrier TAP said.

“There was a bomb threat and the plane was handed over to the authorities for inspection. The passengers have been removed,” he said refusing to provide details on how the threat had been delivered, as Reuters reports.

The flight had been due to take off at 6:05 a.m. (0605 GMT), but was still being searched at 0840 GMT.

A spokesperson for national airport management company ANA said the incident had no knock-effects and no other cancellations or delays were caused, as The Portugal News reports.
