KYIV, Ukraine>> Ukraine said Wednesday that it had drawn on stocks of antiaircraft missiles recently replenished by the United States and other allies to shoot down 29 of 30 missiles and exploding drones that Russia had fired at the country in an overnight barrage.

It was one of the better rates of interception by Ukraine during the war and underscored the impact of having fresh supplies of Western weaponry to bolster a war effort that had struggled mightily in recent months.

In Kyiv, Ukraine, authorities said they had shot down an entire volley of missiles and exploding drones aimed at the capital as the devices approached or soared above the city. The aerial duel, between mostly Western-provided air defense systems and incoming Russian missiles, played out over the city shortly before 3 a.m.

Earlier in the year, Ukraine’s air defense ammunition had run perilously low. Commanders at some batteries said their missiles were being rationed, allowing Russian missiles to streak in unimpeded. President Volodymyr Zelenskyy repeatedly has appealed for additional U.S.-made Patriot air-defense systems.

Zelenskyy reiterated the request Wednesday when missiles or falling debris struck an apartment block in Kryvyi Rih, in central Ukraine, killing eight people and wounding 21. Those missiles were fired after the initial wave early Wednesday.

The Biden administration has decided to give Ukraine one additional Patriot system, consisting of launchers, stocks of missiles and powerful radar antennas for finding targets. Other countries also are considering transferring Patriot launchers to Ukraine. Germany has organized the donation of 100 missiles from its stocks and those of Denmark, the Netherlands and Norway, of which 32 have been delivered so far, German Defense Minister Boris Pistorius said this week.

As the assault played out Wednesday, flashes lit up the skyline, and explosions rang out. One civilian was wounded by falling debris, authorities said.

“The enemy launched another missile attack on the capital,” Kyiv’s military administrator said in a post on Telegram, the social networking site. Typical of recent Russian strikes, the attack combined several types of weapons, including drones and cruise missiles. The tactic is intended to overload Ukraine’s air defenses.

The cruise missiles, launched from bombers flying in Russian air space, were timed to arrive in Kyiv simultaneously with a volley of Iranian-designed Shahed exploding drones. In the overall attack, according to the Ukraine air force, Russia also fired three ballistic missiles, an Iskander medium-range, ground-launched ballistic missile and two air-launched Kinzhal, or Dagger missiles, which are dispatched from airplanes and fly at hypersonic speeds. Ukrainian and Western officials have said that Patriot interceptors are the only defense against the Dagger missiles.

Ukraine shot down five of six missiles and all 24 Shahed drones, the air force said in a statement that could not be confirmed independently.

Ukraine’s interception rate for drones and missiles had fallen in the first months of this year compared with a year earlier, as its air defense ammunition ran low and Russia adapted tactics to evade what defenses there were.

The average shoot-down rate for drones for the 12 months through April was about 80%, data from the Ukrainian air force shows. The interception rate for missiles had fallen in some months this year to less than 50%, the data indicated.

Beyond boosting air defenses, the arrival of American weaponry has helped steady teetering positions along the front line and, soldiers said, slowed a Russian assault in the northeastern Kharkiv region. Troops who had bemoaned a shortage of ammunition again opened fire.
