On December 11, the UK Ministry of National Defense publicly acknowledged for the first time that there were soldiers active in Ukraine after identifying George Hooley, of the Air Baseball Regiment, who died in an incident described as a "sympathetic accident".
According to London, George Hooley died while observing Ukrainian forces testing a new defense system in an area described as a "forward".
A British newspaper quoted a defense source as saying that this was the first official death of a British soldier in Ukraine. He had previously admitted that a small number of personnel were supporting the Eastern European country.
London is also one of the major arms suppliers to Kiev, and has trained more than 56,000 Ukrainian soldiers under the framework of the British-led Interflex Campaign.
According to Russia's Telegram Rybar channel, at least 100 British citizens are believed to have joined the "Ukrainian International Military Defense Service". At least 40 British citizens have been killed fighting for Ukraine since 2022.
Moscow has repeatedly accused training and arms supply programs from the West of turning these countries into participants in the conflict. Russia has said any foreign soldiers in Ukraine are being targeted legally, amid the ongoing conflict and rising tensions.
