TOKYO: Leaders of the group of atomic bomb survivors awarded the Nobel Peace Prize warned on Saturday that the risk of nuclear war was rising, renewing their call to abolish nuclear weapons. “The international situation is getting progressively worse, and now wars are being waged as countries threaten the use of nuclear weapons,” said Shigemitsu Tanaka, a survivor of the 1945 US bombing of Nagasaki and co-head of the Nihon Hidankyo group. “I fear that we as humankind are on the path to self-destruction. The only way to stop that is to abolish nuclear,” he said. In awarding the survivors, the Norwegian Nobel Committee highlighted the devastation of the atomic bombings of Hiroshima and Nagasaki and the Japanese group’s decades-long work to rid the world of nuclear weapons. The group’s endeavours have critical importance in the world today, the committee said. It did not specify any countries. Russian President Vladimir Putin signalled last month that Moscow would consider responding with nuclear weapons if the US and its allies allow Ukraine to strike deep inside Russia with long-range Western missiles.
