Dimitrovgrad is located in Serbia and is the first town that migrants cross after having traversed the border with Bulgaria.
To arrive in Serbia they have to walk through mountains for many hours, but at a certain times of the year the weather can be very harsh. There have been some cases of deaths because of cold or starvation.
Once arrived in Serbia migrants are recorded by the police and have 72 hours to leave the country and continue on the Balkan Route to the north. In Dimitrovgrad we met several members of NGOs. Many of them collect heavy complaints about the treatment of migrants in Bulgaria.
