Serbia's defense ministry says a 20-year old Afghan migrant crossing illegally from Bulgaria has been shot dead, apparently by hunters.

The ministry said Wednesday that its border patrol heard a shot Tuesday night and then discovered six migrants, of whom one had a chest wound. He later died.

The ministry says a hunter who was at the scene was detained on suspicion that he shot the migrant.

Since the so-called Balkan migrant route was closed in March after more than 1 million used it to head for the EU last year, hundreds fleeing wars and poverty are still crossing daily from Bulgaria through Serbia to try to make it into EU-member Hungary.

UNHCR has estimated that there are currently some 4,400 migrants stuck in Serbia.
