SID, Serbia: The first migrants arrived near the Croatian frontier on Wednesday, potentially carving out a new route through Europe after Hungary sealed its borders. The group of 30-40 mostly Syrian or Afghan migrants arrived at the Serbian border town of Sid early in the morning. Until this week, the vast majority of migrants and refugees traveled up from Greece, through Macedonia and Serbia into Hungary. But Hungary sealed its southern border Monday as part of a wider crackdown on migrants entering the country. The new route takes the migrants to Croatia, from where they will have to travel through Slovenia to get to northern Europe.
