Western embassies in Kyiv close due to Russian attack threats

Several Western embassies in Kyiv, including the U.S., closed on Wednesday due to security concerns amid threats of a significant Russian air attack. This decision follows Russia's promise to respond to U.S. support for Ukraine's strikes on Russian targets. The closures come as tensions escalate, with North Korean troops reportedly assisting Russia. Russian President Vladimir Putin has also announced a new nuclear doctrine, allowing for a potential nuclear response to conventional attacks supported by nuclear powers. Ukraine has conducted strikes on military targets in Russia, including a drone factory and an arsenal. Meanwhile, military analysts suggest that U.S. missile support may weaken Russia's military capabilities, although it is not expected to drastically change the war's dynamics.
