Russia says new US nuclear tests could spur dangerous 'domino effect'

Speaking before the Conference on Disarmament in Geneva, Russian ambassador Gennady Gatilov decried US President Donald Trump's announcement last year that his country was prepared to stage its first nuclear test since 1992. "We warn that the US withdrawal from its national moratorium would trigger a domino effect," he said, speaking through a translator, stressing that "the responsibility for the consequences would rest entirely with Washington".
