Ukraine Deploys US Long-Range Missiles in Russia, Escalating Tensions

Ukraine has reportedly used US-supplied Army Tactical Missile Systems (Atacms) to strike Russia's Bryansk region, marking the first use of these long-range missiles on Russian territory. The attack, which followed Washington's approval for such actions, resulted in a fire at a military facility but no casualties. Russia's defense ministry confirmed the strike and warned of a "tangible response." Meanwhile, President Putin has updated Russia's nuclear doctrine to consider attacks from non-nuclear states, backed by nuclear powers, as joint assaults.
