KYIV (Reuters) - Ukrainian investigators have opened a criminal case involving Defence Minister Rustem Umerov, a move likely to deepen a standoff in his ministry over arms procurement that could strain Kyiv's ties with important Western allies.
The National Anti-Corruption Bureau of Ukraine (NABU) told Reuters in a statement that its investigation, requested by a corruption watchdog, would examine whether there had been an abuse of authority by Umerov but gave few other details.
