Japan, Sep 29 (ANI): According to Japanese media, rescuers have found at least five additional people in "cardiopulmonary arrest" at the summit of the Japanese volcano that erupted two days ago. At least 36 people are feared to have died after a Japanese volcano erupted without warning at the weekend, raining ash and stones on hikers. Rescuers at the peak of Mount Ontake found what may be five new victims of the Saturday eruption, which took place as the popular hiking site was packed with climbers, including children, admiring autumn foliage. Four people have been confirmed dead so far in Japan's first fatal volcanic eruption since 1991, and at least 60 have been injured. More than 500 searchers had been combing the summit. Helicopters lifted laden stretchers one by one from the mountain's summit even as the smell of sulphur strengthened at the peak, fanning fears of toxic fumes.
