By SUSIE BLANN (Associated Press) KYIV, Ukraine (AP) — The head of the Russian private army Wagner says his force lost more than 20,000 fighters in the drawn-out battle for Bakhmut, with about 20% of the 50,000 Russian convicts he recruited to fight in the 15-month war dying in the eastern Ukrainian city. The figure was in stark contrast with claims from Moscow that it lost just over 6,000 troops in the war, and is higher than the official estimate of the Soviet losses in the Afghanistan war of 15,000 troops between 1979-89.
