Fire destroyed the camp in Lipa housing about 1,200 people. Police and UN officials have said the blaze was probably started by migrants unhappy at the temporary closure of the camp, scheduled for the same day.
Dozens of men spent the night at a damaged metal container near the site of the fire, where only a ghostly steel construction remained. Smoke was still rising from some burned patches of ground. Bosnia has become a bottleneck for thousands of migrants hoping to reach the EU. Other migrants tried to erect nylon tents and slept fully dressed on the frozen ground.
Most of them walked through the woods towards the town of Bihac, near the Croatian border, avoiding areas marked with warnings about landmines remaining from the Bosnian war in the 1990s. The temperatures were low as -15 degrees Celsius.
