Zelensky aseguró que Rusia utiliza misiles norcoreanos para atacar Ucrania

The Ukrainian president said strikes in Zaporizhzhia - which killed at least six and injured at least 19 - involved ballistic missiles from Russia's ally.

In Voronezh, in southern Russia, warehouses belonging to the online retailer, Wildberries, were hit by Ukraine. The company, known as Russia's Amazon, has been repeatedly targeted in recent weeks.

The attacks come a day after at least 13 people were killed, including one child, in Ukrainian drone strikes on the Russian republic of Tatarstan, more than 1,100 km (680 miles) from the Ukrainian border.

In a video address on Monday evening, Zelensky said "for the first time" Russia "cannot wage war without reinforcements from North Korea".

"The more North Korean strikes there are here in Ukraine, in Europe, the more their missiles and soldiers are used, the more they correct their shortcomings and blind spots", Zelensky said, adding that this poses a danger to the rest of the world.

In his address, Zelensky also hailed a successful air strike on a Russian petrochemical plant in western Siberia on Monday as a "very significant achievement" by the Ukrainian military.

He promised "more Ukrainian deep strikes, which should demonstrate to Russia and the Russians that peace is necessary".

It is not the first time Zelensky has accused Russia of receiving military assistance from North Korea.

He warned over the weekend that as many as 50,000 North Korean soldiers are being sent to join the military campaign defending Russian territory.

Zaporizhzhia Regional Governor Ivan Fedorov posted photos of vehicles and buildings on fire, saying Moscow had struck the city using missiles and guided bombs. In addition to those killed, at least 19 others were injured

One person was injured in strikes on Kyiv, where air raid sirens sounded twice during the night. Explosions could be heard on the outskirts of the capital, triggering fires.
