SEOUL (Reuters) -South Korea's military said on Monday it has detected signs of North Korea preparing to send more troops and weapons, including suicide drones, to Russia to support its war against Ukraine. Pyongyang has already provided 240mm multiple rocket launchers and 170mm self-propelled howitzers to Russia, and was seen preparing to produce more suicide drones to be shipped there after leader Kim Jong Un guided a test last month, according to Seoul's Joint Chiefs of Staff (JCS). "Suicide drones are one of the tasks that Kim Jong Un has focused on," a JCS official said, adding that the North had expressed its intention to give them to Russia.
