North Korea has warned of a nuclear war on the Korean peninsula while vowing to step up its atomic weapons programme in defiance of new UN sanctions.
Today's Rodong Sinmun, a state-run North Korean newspaper, claimed the US has 1,000 nuclear weapons in South Korea. Another state-run publication claimed that America had been deploying nuclear weapons in Japan as well.
