Bomb threats on two passenger planes approaching Brussels' Zaventem airport have proved to be false alarms.
Authorities found nothing unusual on board the aircraft, which both landed safely, Belgian digital media reported.
Zaventem Mayor Ingrid Holemans confirmed to the VTM network that both planes landed without incident, one of them - from Scandinavian airline SAS - having taken off from Oslo and now on the ground in Brussels.
Football commentator Bart Raes posted on his official Twitter account that his plane - the SAS jet from Oslo - had landed and all passengers had been evacuated.
"Passengers were brought up to date at the gate after having to wait on the plane for 10 minutes," he posted, adding that they were now safely at the arrivals hall."

He also confirmed to VTM that passengers received no information about the bomb alert until the aircraft had landed at Zaventem.
The other jet, an Air Arabia Maroc aircraft, was diverted to the southern French city of Toulouse and also landed without incident, according to radio station VRT.
Officials in the office of Belgian Interior Minister Jan Jambon said that the threats were received via an internationally distributed message, although they did not specify the source.
The daily Het Laatste Nieuws, however, reported that the message had been posted on Twitter.
As a result of the bomb alerts, Belgium activated its emergency medical procedures with the Belgian Attorney General's Office saying that the threat was enough to spur the authorities to take the appropriate measures.
The Belgian crisis centre, meanwhile, said that a "report (was received) that had to be taken seriously."
On March 22, Belgium suffered two terrorist attacks at the Zaventem airport and the Maelbeek metro station that resulted in 32 fatalities and hundreds of wounded.
In the months since the attacks, bomb alerts and police operations have multiplied. In two of the police operations, several suspects who allegedly were planning to stage another attack were arrested.
