Stockholm, Shawwal 15, 1439, Jun 29, 2018, SPA -- Sweden is set to step up passport controls at airports and ports across the country amid concerns about the changing nature of security threats, the National Border Police said on Friday. Border controls would be extended because "the threat looks somewhat different than before," dpa quoted a statement released by the border police as saying. Sweden introduced passport controls at its border crossings in the autumn of 2015, to manage the large influx of migrants that entered the country across the Oresund Bridge from Denmark, and at ferry ports in the south of the country. --SPA 03:08 LOCAL TIME 00:08 GMT 0021 www.spa.gov.sa/w710065
