Bomb threats to 11 Tokyo hospitals

No explosives had been found so far at 11 hospitals targeted, Kyodo News agency said. Tokyo Metropolitan Police confirmed that 11 locations had received such threats.

The reported threats come as police have bolstered their presence in train stations and other public places during the campaign for parliamentary elections next week. An anonymous bomb threat last week forced the evacuation of an airliner in northern Japan.

The letters said the bomb attacks would come within 45 days, and at least some of the threats also criticised universities for not accepting enough applicants to their medical schools, Kyodo News agency said.
