AP reporter: Passengers evacuated from Nice airport are being allowed to return

NICE, France -- AP reporter: Passengers evacuated from Nice airport are being allowed to return, pick up their luggage.

Spain says it is maintaining its national security alert at one step below maximum following the Nice attack but has stepped up police controls in transport centers such as airports, tourism sites and places where large numbers of people gather.

Interior Minister Jorge Fernandez Diaz said Spain and France had agreed to continue enforcing tighter police controls at border crossings that were introduced for the recent European football championship and the Tour de France.

Speaking after meeting with Spanish police officials and political party representatives, he said maximum alert level five would be applied only if security officials unanimously felt a terror attack was imminent.
