Russia's Deputy Foreign Minister Andrey Rudenko issued a warning to South Korea against supplying lethal aid to Ukraine, saying that the move would "fully destroy relations" between the two countries.

The Ukrainian military said on Monday that it found Western-made parts inside North Korean ballistic missiles, marking the latest discovery for Kyiv as it continues to find technology from Europe and the US inside weapons used by the Russian military.

Russia and Ukraine have traded air strikes, after a week of intensifying rhetoric in which Russia tested a new missile on Ukraine. Russia has made close to 1,500 strikes on Ukraine since Sunday evening on about half of the country's regions causing dozens of injuries, Ukrainian President Volodymyr Zelensky said.

A swarm of explosive drones bound for Kyiv and other targets interrupted a weeks-long lull in the Ukrainian capital, adding to its darkening mood.
