The United States has accused Russia of a "dangerous and inexplicable escalation" of the Ukraine war, citing the launch of a nuclear-capable Oreshnik ballistic missile near Poland. U.S. Deputy Ambassador to the UN Tammy Bruce condemned the attack and resulting casualties, while Ukraine called for a UN Security Council meeting. Russia, however, blamed Ukraine for the diplomatic impasse. This escalation occurs as the Trump administration seeks peace negotiations and considers new sanctions against Russia.
