Police officers stand guard in a checkpoint near to the border of Spain and France in La Jonquera, Girona, Spain, Saturday, April 28, 2012. Spain has temporarily restored border checks in its northeast and at two major airports in a bid to stop protesters entering the country ahead of a European Central Bank meeting in Barcelona. Spanish authorities early Saturday suspended the Schengen Treaty which allows unrestricted travel inside member nations, and imposed controls at six border crossings with France and at Barcelona and Gerona international airports.
