The Japanese city of Hiroshima has asked Pokemon Go's creators to keep its virtual monsters out of memorials to victims of the atomic bomb.
It wants the monsters removed by 6 August, when an annual ceremony is held on the anniversary of the 1945 bombing.
It follows a request by the operators of the Fukushima nuclear plant - highly radioactive after its 2011 meltdown - to keep Pokemon out of its plants.
The wildly popular Pokemon Go was released in Japan on Friday.
