In the video, which allegedly aired on Russian television, the man appears to be giving his name as Andrew Hill. He speaks with an English accent, has his hand on a slingshot, a bandage around his head and blood appears on his hand. The unverified video has been leaked to the internet. The Bureau of Foreign Affairs, Commonwealth and Development (FCDO) said it was urgently seeking more information and was supporting family members. “The FCDO condemns the exploitation of prisoners of war for political purposes and calls on anyone detained to be treated humanely in accordance with the requirements of international humanitarian law,” he said.

Urey, born in 1977 in Manchester, and Healy, born in 2000 in Cambridgeshire, traveled to Ukraine of their own free will, the group said. He did not work for the Presidium Network, which assists in providing assistance to Kyiv. The group said the couple was driving to help a woman and two children move away when they disappeared.

Meanwhile, in a briefing on Saturday, the UK Department of Defense (MoD) said Russia had faced “significant challenges” and that troops were likely to suffer from “weakened morale”. In a Twitter post, the Foreign Ministry said: “Russia hopes to address issues that have previously limited its invasion by geographically concentrating combat power, shortening supply lines and simplifying command and control. “Russia continues to face significant challenges. He was forced to merge and redeploy exhausted and disparate units from the failed advances in northeastern Ukraine. “Many of these units are likely to suffer from poor morale. “There are still shortcomings in Russia’s regular coordination. “The lack of unit-level skills and inconsistent air support have left Russia unable to fully utilize its battlefield, despite local improvements.”
