In Bosnia and Herzegovina, a crisis is looming if the pace of coordinated humanitarian response does not pick up before temperatures begin to drop. More than 4,000 migrants and refugees are currently sheltering in informal camps and squats along Bosnia’s border with Croatia. This is a new situation for Bosnia, which before this year had not seen significant numbers of people transiting through the country as part of the so-called Balkan route. Although the stream of people arriving in the country has been rising for months, basic humanitarian conditions in the two largest points of congregation along the border remain alarmingly inadequate.
