Bomb threats have been reported on two planes due to land shortly at Brussels airport in Zaventem, Belgian state broadcaster VRT said.

Federal prosecutors are taking the threats seriously, VRT said.

Dutch journalist Bart Raes said that he was on a flight from Oslo that received one of the bomb threats.

He said the plane had received the threat around 20 minutes before landing, in a post on Twitter in Dutch.

He said the plane has now landed safely and the passengers are being removed.
