Belgrade, Dhu-AlQa'dah 7, 1436, Aug 22, 2015, SPA -- Thousands of migrants on Saturday broke through Macedonian police barricades at the border with Greece, local media reported. According to dpa, police used stun grenades for the second time in two days in a bid to keep them out, but were overwhelmed. Security forces had strengthened the barricades along the Greek border, where the mainly Middle Eastern migrants have been stranded in a no-man's land for several days. Police, who have received military support since Macedonia declared a state of emergency on Thursday, stretched a second line of barbed wire between Macedonian territory and the stranded migrants, A1 TV reported. An estimated 826 migrants deemed to be "vulnerable" - mostly women and children - were allowed to pass through in the period since the border was closed, allowing them to reach the nearby train station in Gevgelija. --SPA 21:23 LOCAL TIME 18:23 GMT www.spa.gov.sa/w
