In Bosnia, players are at risk of wandering into mine fields, group says

(CNN) A Bosnian nongovernmental agency is urging Pokemon Go users to be aware of their surroundings, for a good reason -- land mines.

Distracted users are roaming into areas dotted with the unexploded ordnances (left over from the 1990s conflict in that region) while trying to catch the virtual reality monsters, Posavina bez mina said on its Facebook page.

"We received information that there are cases where users of the Pokemon Go app in Bosnia are entering into mined forests and risky areas in order to find Pokemon," it said this week.

"We ask all citizens to respect all signs warning them about mines and to not enter areas unfamiliar to them."
