The airports affected were Toulouse, Biarritz and Pau in the south-west, Nice in the south-east, Lyon in the east, Lille in the north, and Rennes and Nantes in western France, the national aviation authority and Interior Ministry said. A spokesman for DGAC aviation authority confirmed bomb warnings and evacuations at four of the airports – Lille, Lyon, Toulouse and Beauvais.<b> </b><a href="https://www.thenationalnews.com/tags/security/" target="_blank">Security </a>officials wanted to “clear up any doubts” the threats might be real, a source said.
