In this photo taken Friday, Feb. 5, 2016, unaccompanied minors pull sleds up a small hill after a ride in Alta, northern Norway. As asylum-seekers stream into Europe, the number of unaccompanied children and teenagers among them overall is soaring. In Norway and Sweden, about one in five last year was a minor traveling alone, up from one in 10 the year before. (AP Photo/Alastair Grant)
