Russia has retaken about two-thirds of the territory Ukraine seized last summer in the Kursk region of Russia, but at a fearful cost in lives.

South Korea’s spy agency says North Korea appears to have sent additional troops to Russia, after its soldiers deployed on the Russian-Ukraine fronts suffered heavy casualties.

North Korea recently sent some 3,500 additional soldiers to Russia's Far East for field training, a South Korean lawmaker said Wednesday, with the possibility of soon being dispatched to the front lines.
