U.S. embassy in Kyiv closes as Ukraine prepares for potential air attack

The U.S. has temporarily closed its embassy in Kyiv and instructed staff to shelter in place due to a warning of a significant air attack. This follows reports of explosions in the Ukrainian capital, indicating heightened tensions. Ukraine has launched ATACMS missiles into Russia for the first time in nearly three years, targeting an ammunition site. This escalation coincides with Russia's adjustment of its nuclear policy, lowering the threshold for potential nuclear responses. The conflict has intensified as both sides face increased pressure. U.S. officials are concerned about Russia's military support from North Korea, while Ukraine continues to endure drone and missile attacks on civilians.
