President Volodymyr Zelenskyy warns that Ukraine is running critically low on US-made air-defense supplies, including Patriot missiles, in a letter to US President Donald Trump and to the US Congress, according to reports seen by Bloomberg. Zelenskyy says the shortfall threatens Ukraine’s ability to intercept Russia’s ballistic missiles.

Both outlets describe the appeal as urgent, tied to continued and intensified Russian missile and drone attacks on Ukraine, including threats of renewed strikes on Kyiv. The Kyiv Post adds that Ukraine’s Presidential Office later confirms the existence of the letter.

The reports do not provide details on the specific quantities involved or the timing of any potential US resupply. They also do not specify whether the letter requests particular actions beyond addressing the air-defense shortage. The warning places additional focus on the availability of anti-ballistic air-defense systems as Ukraine continues to respond to Russia’s ongoing campaign of attacks.
