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.

Russia's military captured a British national fighting with Ukrainian troops who have occupied part of Russia's Kursk region, according to reports Monday, as Moscow began daylight drone attacks on civilian areas of Ukraine and its ground forces accelerated gains along parts of the front line.

Video posted on Russian social media channels showed a young bearded man in military clothing. The captive said he was a former British soldier.
