The U.S. military is facing a severe shortage of Patriot interceptor missiles, with current stockpiles reportedly at only 25% of the level required for potential conflicts. -This depletion, exacerbated by the recent defense of Al Udeid Air Base against an Iranian missile barrage and extensive aid

The US defence department halted some shipments of critical weapons last week, raising concerns in Kyiv that its air defences could run low in a matter of months.

The US Army is closely watching how Ukraine uses its Patriot air defenses to stop Russian attacks.

Kyiv is again under a massive overnight Russian drone attack, local officials say, with at least eight people reported injured and fires burning across the city.

A Russian drone barrage targeted the center of Kharkiv on Friday, injuring nine people and damaging a maternity hospital in Ukraine’s second-largest city, officials said.

"Right now, our priority is strengthening air defences. Russia wants to move on to using 1,000 drones in the space of a single attack," Zelenskiy wrote.
