According to state-run RTS television, one migrant was killed and at least six others were injured in a shootout between migrant groups in Serbia near the Hungarian border on Saturday.
According to RTS, the 16-year-old girl suffered life-threatening injuries in the incident, which occurred in a forest on the outskirts of Subotica, about 160 kilometres (100 miles) north of Belgrade, where the injured were hospitalised.
Police blocked access to the forest where the incident occurred, which was only about a kilometre from the Hungarian border.
Aleksandar Vulin, the Interior Minister, rushed to the scene.
According to Subotica mayor Stevan Bakic, the injured, aged 20 to 30, do not have any identification.
It is unknown what caused the incident, he added.
According to local media, the shootout took place between Afghan and Pakistani migrants, most likely over human trafficking from the region to European Union member Hungary.
Serbia is located on the so-called Balkans route, which is used by migrants fleeing war and poverty in the Middle East, Asia, and Africa.
Despite the fact that the route is no longer as busy as it was during Europe’s migrant crisis in 2015, tens of thousands of illegal migrants cross the region each year.
