Brussels, Safar 23, 1437, Dec 5, 2015, SPA -- EU member states backed measures Friday to extend border controls within Europe's passport-free Schengen zone for up to two years if necessitated by the migration crisis and Greece's difficulties in controlling its external frontiers, dpa reported. The European Union is contending with its largest population movements since World War II. More than 950,000 people have reached the continent this year, many fleeing war-torn Syria. -- SPA 01:14 LOCAL TIME 22:14 GMT www.spa.gov.sa/w
