At least four people were killed and 15 more were wounded in a combined Russian missile and drone attack on Ukraine’s Kyiv region overnight, Ukrainian President Volodymyr Zelenskyy said on Saturday.

Three of the wounded were in critical condition, of whom two were undergoing surgery, regional administration head Mykola Kalashnyk reported. The attack hit four districts, damaging residential buildings, educational institutions, enterprises and critical infrastructure, Kalashnyk said in a social media post, adding that he had “information about 30 damaged sites”.

Zelenskyy said the main target for the overnight strikes was “the energy infrastructure of the Kyiv region.” He said Russia had launched 430 drones and 68 missiles, adding that air defences had intercepted 402 and 68 of them respectively.

Zelenskyy said rescue and clearing up operations were underway “in the Kyiv, Sumy, Kharkiv, Dnipro, and Mykolaiv regions”.

Russia’s Defence Ministry on Saturday said the nighttime strikes targeted energy and industrial facilities serving Ukraine’s armed forces, as well as military airfields.

Peace talks stall amid Middle East war

The strikes came days after the US postponed peace talks between Russia and Ukraine scheduled for this week, citing the war in the Middle East.

Russia is already profiting from a surge in global energy prices, and could hope that the US-Israeli war with Iran will detract attention from Ukraine and deplete Western arsenals.

Zelenskyy on Saturday called on Kyiv’s Western partners to pay “one hundred percent attention” to the need to boost the production of air defense missiles.

“Russia will try to exploit the war in the Middle East to cause even greater destruction here in Europe, in Ukraine,” he said in a post on social media.

“We must be fully aware of the real level of the threat and prepare accordingly, namely: in Europe, we need to develop the production of air defence missiles — especially those capable of countering ballistic threats — as well as all other systems necessary to truly protect lives,” he said.

Zelenskyy also expressed concern that the temporary easing of US sanctions on Russian oil would bring Moscow new revenue to finance its war effort.

Ukrainian drones reportedly hit Russian oil refinery and port

Overnight into Saturday, Ukrainian drones hit an oil refinery and port in Russia’s southern Krasnodar region, local Russian officials reported.

Krasnodar authorities said three people were hurt in a strike on Port Kavkaz, a port opposite Crimea used to ship liquefied natural gas and grains. A service vessel and pier infrastructure were damaged, they said in a social media post. One person was hospitalized, they added in a separate post later.

Falling drone debris also sparked a fire at the region’s Afipsky oil refinery, local authorities said. They added no one was hurt, and that the strike damaged the refinery, allegedly due to falling drone debris.

Russia’s Defence Ministry said air defences “intercepted and destroyed” 87 Ukrainian drones overnight across multiple regions.

Earlier this week, Russian and Ukrainian officials both claimed frontline progress, with Ukraine saying it pushed Moscow’s forces back across places on the front line and the Kremlin insisting Russia’s invasion of its neighbor is making progress.

Russia’s full-scale invasion sparked the bloodiest war in Europe since World War II, forcing the displacement of millions and killing hundreds of thousands of soldiers and civilians on both sides.
