KIEV, Ukraine (AP) -- Two people have been injured while bowling in a rebel-controlled area of east Ukraine after a player rolled a grenade instead of a ball. A separatist-run news agency cited emergency services official Sergei Ivanushkin as saying Friday that the separatist-held parts of Luhansk region have seen a spate of accidents recently because of careless use of explosives. Ivanushkin said a man and woman were hospitalized after Thursday's incident. The blast occurred at a "cheburechnaya" -- a restaurant serving fried pastries -- that also offered duckpin bowling, which uses a ball without holes on a relatively short lane. East Ukraine has been wracked by war for almost a year, during which time the region has become flooded with small arms and grenades.
