Twenty-nine migrants were injured in a fire that broke out early on Saturday at a migrant camp in the northwestern Bosnian town of Velika Kladusa, police said.
Regional police spokesman Ale Siljdedic said the injured were taken to hospitals in Velika Kladusa and neighbouring Bihac following the fire at the Miral camp, which is used as temporary accommodation for about 500 migrants.
"Fire brigades are on the site and will soon put down the fire, when the investigation into the incident could start," he told Reuters.
Videos posted on social media showed several people jumping in panic out of the camp's windows.
About 25,000 people from Asia and North Africa entered Bosnia from Serbia and Montenegro last year, and about 6,000 have arrived in the impoverished Balkan country this year, according to Bosnia's security agencies.
