Ukraine's military intelligence chief says North Korea is currently Russia's largest supplier of arms.
Kyrylo Budanov told the Financial Times in an interview published on Sunday that North Korea has transferred a significant amount of artillery ammunition to Russia. He said Russia is using more weapons and munitions in Ukraine than it can produce.
Budanov said North Korea's transfer of arms to Russia allowed Russia to breathe a little. He said that without North Korea's help, the situation would have been catastrophic for Russia.
Russian attacks continue in Ukraine. One person was reportedly killed on Monday in Kramatorsk, a city in the eastern region of Donetsk. A fire is reported to have broken out at a power distribution company's facility in the eastern region of Kharkiv, causing power outages in surrounding areas.
In a Russian-controlled area of the Donetsk region on Sunday, 27 people were killed in what Russia said was a Ukrainian attack. Ukrainian media reported that a fire that broke out at a gas company's facility at a port in northwestern Russia was the result of an attack by Ukraine's security agency.
In response to the assault in Donetsk, Kremlin spokesperson Dmitry Peskov said on Monday that Russia will continue its special military operation to protect Russian people and infrastructure.
