Russell Bentley, 64, who fought alongside pro-Putin rebels in eastern Ukraine, was tortured and murdered by Russian servicemen, Kremlin investigators said on Friday. Bentley, a self-described communist from Dallas, Texas, went missing in the Russian-occupied city of Donetsk in April and was later found dead. Nicknamed “Texas”, he regularly appeared on pro-Kremlin social media channels, backing Moscow’s full-scale military offensive.
