Ukraine’s parliament on Tuesday appointed Ruslan Kravchenko, one of the key investigators of alleged Russian war crimes during the occupation of the Kyiv region in 2022, as prosecutor general.

Axar.az reports, citing Reuters, Kravchenko, 35, is now head of the state tax administration, and before that chaired the Kyiv region military administration.

He was involved in the recording and prosecuting of alleged Russian atrocities in the town of Bucha, which was occupied for 33 days in the early stages of Moscow’s full-scale invasion. Russia denies accusations of numerous executions, rapes and torture during the occupation.

Kravсhenko was also a prosecutor in Ukraine’s ousted President Viktor Yanukovych’s treason case.

The prosecutor general’s post has remained vacant since October, after Andriy Kostin resigned following a scandal around officials receiving fake disability status and avoiding military service.
