France will reinstate controls on its borders normally open to other countries in Europe's free-travel zone for the period around a major U.N. climate conference in Paris, AP quoted the interior minister as saying Friday. Authorities are on alert for violent protesters as well as potential terror attacks. Bernard Cazeneuve said on BFM television Friday that the controls will be in place for a month as part of larger security measures around the Nov. 30-Dec. 11 conference. He did not elaborate on how tightly the borders would be controlled or how the border checks would be carried out. Europe's so-called Schengen zone of countries with open borders does allows for occasional reintroduction of internal border checks, which some countries have done amid this year's migrant crisis.
