A spokesman for said the airport confirmed to the Local Austria that they are intensively monitoring the situation and are in close contact with local police and security authorities.

Information about the explosions at Brussel's Zaventem airport and Maalbeek metro station, close to many EU institutions, is still emerging, although a Belgian prosecutor has confirmed that the blasts at the airport were likely to be suicide bombings. Some reports in Belgian media suggest at least 13 people have been killed.
The airport has cancelled all flights between Vienna and Brussels for today and they recommend all passengers check additional information regarding their flights with their airline. One Austrian Airline flight that was already in the air when the attack happened, was diverted.
Belgium has now raised its terror threat to its highest level, and many airports around Europe have also been put on high alert.
In Paris authorities immediately raised the terror alert at the city's airports and reinforced security. There was also an alert at Gare du Nord station in Paris, where trains depart to Brussels and London, although it proved to be a false alarm.
German police are also tightening security at the country's largest airport in Frankfurt.
In Spain the airports are not currently on high alert, although they said this could change throughout the day.
