US closes embassy in Kyiv amid concerns over potential air attacks

The U.S. embassy in Kyiv has closed due to concerns over a potential air attack, following Ukraine's use of ATACMS missiles against Russia. Embassy staff are instructed to shelter in place, and U.S. citizens are advised to prepare for air alerts. Ukraine's missile strike on Russia's Kursk marks a significant escalation, as these long-range missiles were previously restricted from use on Russian territory. The U.S. decision comes amid reports of North Korean soldiers assisting Russia. This development may shift the dynamics of the conflict, prompting NATO allies to reconsider their restrictions on military support for Ukraine. Ukraine has also launched UK-made Storm Shadow missiles at Russia.
