Israel's envoy to Japan has hit out at authorities in Nagasaki after they declined to invite him to a peace ceremony commemorating the 1945 atomic bombing of the city, accusing the local mayor of "inventing" security fears. The decision by Nagasaki contrasts with that of Hiroshima, which will host its ceremony on Tuesday and invite Israel. Both cities had been under pressure from activists and bomb survivor groups to exclude Israel due to its bombardment of Gaza, where tens of thousands of Palestinians have been killed since Israel began targeting militant group Hamas following the 7 October attack. Russia and Belarus have both been disinvited over Moscow's invasion of Ukraine, and campaigners had hoped Nagasaki and Hiroshima - which both suffered the horror unleashed by nuclear weapons at the end of World War II – would do the same.
