France will install security gates at stations serving Thalys cross-Europe trains, operating on the territory of France, Belgium, the Netherlands and Germany, according to a statement by the Minister of Ecology, Sustainable Development and Energy, Segolene Royal. Additional security measures will be introduced by December 20 in the French cities of Paris and Lille, she said. "If necessary, France will install the gates [in Brussels, Amsterdam and Cologne], so they will be similar to the equipment installed in Paris and Lille," Roayl said, as quoted by the France Inter radio station. The anti-terrorism measures come as a response to the November 13 series of coordinated attacks and suicide bombings in the French capital that killed 130 and injured over 360.
