Putin escalates nuclear threat after US backs Ukraine's missile use against Russia
Vladimir Putin has increased the threat of a nuclear attack in response to the U.S. allowing Ukraine to use longer-range missiles against Russia. He signed a revised nuclear doctrine stating that any conventional attack on Russia supported by a nuclear power will be viewed as a joint attack. The updated doctrine specifies that a significant aerial attack on Russia could lead to a nuclear response. This change follows President Biden's decision to support Ukraine's military actions, which have included recent gains in the Kursk region. China has reportedly cautioned Russia against using nuclear weapons amid ongoing conflict, which has resulted in heavy casualties on both sides. The U.S. plans to announce additional military assistance for Ukraine, while the UK continues to advocate for stronger weapon supplies.
