UN chief urges US, Russia to negotiate new nuclear treaty amid growing arms risks

UN Secretary-General Antonio Guterres called on the US and Russia to negotiate a new nuclear arms control treaty, warning that 'rattling of nuclear sabers' is growing louder as arsenals expand. This marks a renewed high-level push for arms control amid deteriorating US-Russia relations and the expiration of New START in 2026. The call signals growing international concern over nuclear escalation risks, though no concrete negotiation framework has been proposed.
