VIENNA, Austria, Muharram 11, 1437, Oct 24, 2015, SPA -- Amnesty International is warning of a humanitarian disaster unless countries on the Balkans migrant route come up with a plan at a summit this weekend on how to tackle the crisis, AP reported. The group's branch in Slovenia said in a statement Saturday that migrants are still often forced to sleep outside on their way to Western Europe, and that conditions will become more severe as winter set in. The group says Sunday's summit in Brussels of several EU and Balkan nations must result in a solution. Leaders "must not walk away from another meeting without a feasible plan on how to protect the needs and rights of the refugees," the group insists. --SPA 13:28 LOCAL TIME 10:28 GMT www.spa.gov.sa/w
