Air defense has been activated in Kyiv amid reports of airstrikes targeting Chernihiv, a city in northern Ukraine, ABC News confirmed.

Ukraine’s shock drone strike on Russia’s strategic bomber fleet this week has generals and analysts taking a new look at threats to high-value United States aircraft at bases in the homeland and abroad – and the situation is worrisome.

The targets were Russian warplanes, including strategic bombers and command-and-control aircraft, worth hundreds of millions of dollars. The weapons were Ukrainian drones, each costing under $1,000 and launched from wooden containers carried on trucks.

NBC News has analyzed satellite imagery to dig into the claims being made by Kyiv and Moscow as part of a wider propaganda war being waged in parallel to the actual fighting.

Ukrainian President Volodymyr Zelenskyy said emergency operations were underway across multiple regions to clear debris and rescue victims possibly trapped under rubble.

China said on Saturday it was willing to accelerate the examination and approval of rare earth exports to European Union firms.

The Pentagon notified Congress last week that it will be diverting critical anti-drone technology that had been allocated for Ukraine to US Air Force units in the Middle East, according to correspondence obtained by CNN and people familiar with the matter.

KYIV, Ukraine (AP) — Russia struck Ukraine with a thunderous aerial bombardment overnight, further dampening hopes that the warring sides could reach a peace deal anytime soon days after Kyiv embarrassed the Kremlin with a surprising drone attack on military airfields deep inside Russia.

The move underscores the Trump administration’s waning commitment to providing military aid to Kyiv.

Russia bombarded Ukraine’s second-largest city with massive strikes in the early hours of Saturday, its mayor said, one night after Moscow carried out one of the war’s largest aerial assaults on Ukraine.

Ukraine’s president wants his Western backers to speed up deliveries of air defense systems to counter Russian missile strikes.
