North Korea is expanding a weapons plant that manufactures missiles used by Russia against Ukraine, according to new research from a US-based think tank.

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.

North Korean troops reportedly deployed in Ukraine, prompting U.S. and allies' concern over escalating tensions with Russia.

Russia has begun luring Yemeni men to fight in its war in Ukraine by falsely promising lucrative jobs before forcing them to sign military contracts and then sending them to fight on the front lines.

Russian state media reported that a British volunteer for the Ukrainian Army was captured amid fighting in the Kursk region.
