BIHAC, Bosnia-Herzegovina — A prominent humanitarian group is warning that migrants trying to reach Western Europe are living in ìdangerously cold and harsh conditionsî in Bosnia, where hundreds rallied on Friday amid tensions over the influx of people fleeing war and poverty.

The protesters in the northwestern city of Bihac demanded the closure of overcrowded refugee camps and the relocation of the migrants from the city area. They carried banners reading ìFree Bihac!î and chanted anti-migrant slogans.

Bosnia has been overwhelmed by the arrival of migrants heading toward Europe along the so-called Balkan route. Most migrants flock to the northwest section, which borders European Union member Croatia.

This has led to tensions in the border area, with local authorities demanding that other parts of the country share the migrant burden and take in some of the more than 6,000 people staying in the area.

The Doctors Without Borders group warned that ìpeople may die without adequate shelter and other basic servicesî in Bosnia, where many migrants are sleeping in makeshift shelters and abandoned homes.

ìFour official centers for migrants exist, but services are inadequate and tensions are high, leading most people to stay elsewhere,î the report added.

It singled out the improvised Vucjak refugee camp in northwestern Bosnia, describing it as a ìdangerous and inhumane placeî that does not meet minimum living standards. The camp is located on a landfill and next to a minefield from the 1992-95 Bosnian war.
