Ukrainian President Volodymyr Zelenskyy on Monday urged NATO allies to provide additional Patriot interceptor missiles following a massive Russian attack against Kyiv that killed at least 23 people and injured more than 100 others.

"Our warriors performed well today in intercepting drones and cruise missiles, but unfortunately not Russian ballistic missiles," Zelenskyy wrote on X. "And the reason lies in the insufficient supply of interceptor missiles.

"It is critically important that the world – first and foremost the United States and our European partners – come out of the NATO Summit in Ankara with strong decisions in support of our air defense, and thus the protection of ordinary people's lives.

"As long as Patriot missiles remain in our allies' stockpiles, Russia is only encouraged to keep 'vanquishing' residential buildings. The United States and Europe have enough strength to stop this terror."

Russia launched waves of missiles and drones against Kyiv overnight Monday, just hours after Zelenskyy warned of yet another large-scale attack targeting the capital.

Authorities told the Kyiv Independent that at least 16 people were killed and more than 90 others were injured in Kyiv, including six children. Ukraine's State Emergency Service added that search-and-rescue operations were ongoing as of 9:29 p.m. local time at two apartment buildings damaged by the attack in Kyiv's Podil and Darnytsia districts.

Authorities added that seven people were killed and 29 others were injured in the town of Vyshneve, about 16 miles southwest of Kyiv.

Russia's nearly unimpeded strikes are the consequence of a global dearth of interceptors for the U.S.-made Patriot antimissile system, a shortage compounded by the U.S. conflict with Iran.

Ukrainian Defense Minister Mykhailo Fedorov wrote Monday on X that Russia is "exploiting the critical shortage of interceptor missiles for Patriot air defense systems" by "deliberately escalating its use of ballistic missiles, launching them at a scale not previously seen."

"Worldwide, fewer Patriot interceptor missiles are produced each month than Russia launches against Ukraine over the same period," Fedorov said.

Zelenskyy is expected to meet with world leaders, including President Donald Trump, later this week on the sidelines of the NATO summit, which begins Tuesday in Ankara.

It is difficult to say precisely how many Patriot interceptors remain in Ukraine's stockpile because such data is classified. At the end of June 2025, Ukraine reportedly had as few as 16 Patriot interceptors remaining, according to The New York Times.

Ukraine is one of about 20 countries waiting in line for Patriot interceptors, whose stockpiles are low and which can take more than two years to manufacture, The Wall Street Journal reported Monday.

Fedorov said he is planning to hold a series of talks Monday with "the defense ministers of countries that have Patriot interceptor missiles in their stockpiles."

"We have already signed contracts for Patriot interceptor missiles and continue to secure additional agreements, with deliveries scheduled to begin next year," Fedorov wrote. "Our appeal to our partners is straightforward: transfer missiles from your stockpiles now, and replenish them later through our future deliveries.

"A simple decision by our partners to temporarily transfer missiles from their stockpiles will save countless Ukrainian lives. We cannot allow bureaucratic caution to become an obstacle to protecting human life. These missiles belong in Ukraine's air defense system now — not sitting in stockpiles."
