PARIS, March 22. /TASS/. The French authorities have made a decision to beef up transport security in Paris following the Tuesday blasts in Brussels.

"Security has been tightened at airports, railway terminals and at all public transport in the Paris region of Ile de France," the prefecture of the French capital said.

"After the November terrorist attacks in Paris, the security services in the capital's airports work operate in emergency mode, but we are preparing to take additional measures. It is possible," the company’s press service said earlier.
