Brussels, Aug 11: Two planes landed safely at Zaventem airport here on Wednesday (Aug 10) evening after receiving bomb threats, Belgium's state broadcaster VRT reported.
State authorities said an investigation was launched into the incidents and also added that the bomb squad had not been deployed to the airport.
Police sources at the airport said no bomb alerts were issued and the airport had no problems.
The aircraft came from Oslo, Norway and Arlanda, Sweden.
A Dutch journalist, who was on board the flight from Oslo, tweeted that the pilot of the plane received the bomb threat 20 minutes prior to its landing.
Bart Raes, the journalist who works with Belgian broadcaster Woestijnvis/Proximus TV, said the passengers were told about the threat and they had to wait for 10 minutes before disembarking, Reuters reported.
The country's media said some other flights were diverted to other airports.
Twin attacks by Islamic terrorists struck Brussels airport and a metro station in March, killing over 30 people.
