WARSAW, Poland -- The Auschwitz-Birkenau State Museum says it does not allow people to play "Pokemon Go" on their smartphones during visits to the former German death camp because it is "disrespectful on many levels."

"Pokemon Go" is a hugely popular new reality game that uses GPS and allows players to search locations in the real world to find virtual little creatures.

There have been reports of people playing the game at Auschwitz and other sombre memorial sites across the world.

The Auschwitz memorial wrote Tuesday on Twitter: "Do not allow playing @PokemonGO on the site of our Memorial and similar places. It's disrespectful on many levels."

The museum could not be reached for comment Wednesday on the matter.
