At least six people have died in Ukraine, after Russia launched hundreds of drones as far as Ukraine's western regions bordering NATO.
The attack represents one of the longest and largest attacks in Russia's war in Ukraine , Zelenskyy said.
"Since midnight, at least 800 Russian drones have already been launched, and the attack is ongoing, with additional drones entering our country's airspace," he wrote on X.
Zelenskyy said the attack was "deliberately targeting our railway infrastructure and civilian sites in our cities." The overnight strikes targeted Ukraine's residential and railway infrastructure in the central Dnipro and northeastern Kharkiv regions, port infrastructure in the southern Odesa region, and energy facilities in the central Poltava region, according to Zelenskyy.
He added that Ukraine's western regions, closest to the borders with NATO countries, were targeted.
The Polish army said it had scrambled fighter jets as a preventative measure due to the Russian air strikes on Ukraine.
Russia has denied targeting civilians, despite thousands of them dying in its attacks against Ukraine.
"In this difficult geopolitical moment, Russia is clearly trying to disrupt the overall political atmosphere and draw attention to its evil — seeking to do so at the expense of Ukrainian lives and Ukrainian infrastructure," he wrote on X.
"It is important to support Ukraine and not remain silent about Russia’s war. Every time the war disappears from the top of the news, it encourages Russia to become even more savage,” Zelenskyy said, a reference to the world's attention being caught by the Iran war.
On Tuesday, prior to the attack, Trump said he believes Moscow and Kyiv will soon reach a deal to end fighting. "The end of the war in Ukraine I really think is getting very close," Trump told reporters as he left for Beijing.
Russia's use of drones 'evolving' Serhiy Beskrestnov, an adviser to the defense minister, said the attack involved large numbers of drones moving along between 5 kilometers and 10 kilometers (between 3 and 6 miles) from the Belarus border with the aim of overwhelming Ukraine's air defenses and break through to the western regions.
Beskrestnov noted that the strike highlighted the evolving use of drones by Moscow, with tactics changing from attack to attack.
Russia has denied intentionally attacking civilians, despite thousands of them dying in its attacks against Ukraine. Moscow has said strikes on civilian infrastructure are legitimate if they weaken Ukraine's ability to fight.
