Stansted Airport has increased its police presence in the wake of the Brussels bombings today (Tuesday).

Flights are unaffected, the airport says.

A spokesman said: “In response to this morning’s events at Brussels Airport, the police presence has been increased in landside areas at Stansted Airport.

“It is important to note that these are precautionary measures and we continue to closely monitor the situation.

“No airlines at Stansted offer direct flights to Brussels. All other flights are currently operating as normal.”

At least 21 people have died in explosions as part of a suspected terror attack in Brussels this morning, at the city’s main airport and at a Metro station near to the European Parliament building.

The first explosions were heard at Brussels Airport, during the morning rush hour.

Brussels Airport spokeswoman Anke Fransen said: “There were two blasts in the departure hall. The first aid team are in place for help.”

Another explosion has been reported at Maelbaek Metro station. Both the airport and Metro system have been closed following the attacks.

A fire service spokesman said there were 11 dead at the airport and “around 10” at Maelbeek station, where “there was a very big explosion.”

Richard Howitt MEP, who had used the Maelbaek station 30 minutes prior to the explosion, tweeted: ““Belgian media say 11 dead in #Brussels Airport bomb. We stand in silence but now proceed with vote in parliament. Democracy must always win.”
