An airport located at the Swiss-French border was evacuated and then reopened due to a bomb alert, the French police said, just hours after a ‘massive, coordinated arson attack’ disrupted France’s rail network ahead of the Olympics opening ceremony on Friday.

Basel-Mulhouse airport’s terminals were evacuated on Friday morning and all flights had been suspended. 

‘For safety reasons, the terminal had to be evacuated and is currently closed,’ the Basel-Mulhouse EuroAirport had said on its website. 

But now the airport’s site says that it has ‘reopened and all flight operations are gradually restarting’. 

This comes in the midst of Olympic Games chaos after fires were started at France‘s key installations last night, bringing trains to a halt and affecting around 800,000 passengers, with just hours to go before the Olympics opening procession on the River Seine.

While no claim of responsibility has been made and French authorities are yet to name suspects, there is a clear correlation between the targeted attacks and the Olympics getting underway. 

Concerns have been raised that Moscow may be behind the attack. 

Kirill Gryaznov, 40, was arrested on Wednesday and charged with working ‘with a foreign power to try and incite hostilities in France’ after being identified as working for the FSB, Vladimir Putin‘s domestic intelligence agency.
