Ukrainian authorities are investigating 260 criminal cases involving alleged "violations" at military recruitment offices, the State Bureau of Investigations (SBI) said on Tuesday. President Volodymyr Zelenskiy dismissed the heads of regional recruitment centres in August after widespread allegations of criminal abuse and corruption. Kyiv is aiming to improve military recruitment as it presses on with a more than four-month-old counteroffensive to drive Russian forces out of territory in the east and south of Ukraine following Moscow's full-scale invasion last year.
