Pro independence supporters hold banners calling for voting Yes on a planned independence referendum in the Catalonia region, during a demonstration in Barcelona, Spain, Sunday, Sept. 17, 2017. The Spanish government has vowed to stop the planned Oct. 1 vote that it calls illegal. But Catalonia's leaders have pushed ahead even after Spain's Constitutional Court suspended the law passed by Catalonia's regional parliament that convoked the referendum. (AP Photo/Emilio Morenatti)
