North Korea has sent over 13,000 containers of weapons to Russia since mid-2022, according to a South Korean military intelligence report cited by Yonhap.

Intelligence estimates suggest around six million 152-mm artillery shells were shipped from the North Korean port of Najin during this period. North Korea may have also provided Russia with 122-mm artillery shells, as well as mobile anti-aircraft and anti-tank missiles.

The report states, "To prepare for a protracted war in Ukraine, Russia has officially registered North Korea as a base for weapons and ammunition supplies."
