Though North Korean ballistic missiles account for only a small portion of Russia's missile strikes they carry a large warhead of up to one tonne and have a range of up to 800 km, the military source said. The Iskander-M, an equivalent Russian missile, carries a smaller payload and has a shorter range of 500 km.

In an interview with the Associated Press on Feb. 2, Zelensky added that while these countries had previously cooperated on weapons and technology, they are now openly engaged in Russia’s war against Ukraine.
