Ukraine's Zelenskiy says Putin killed mercenary boss Prigozhin

Ukrainian President Volodymyr Zelenskiy said on Friday Russian leader Vladimir Putin was behind the death of mutinous mercenary boss Yevgeny Prigozhin, who died in a plane crash with his top lieutenants last month.

Zelenskiy, who provided no evidence to back up his assertion, made the comment in passing at a conference in Kyiv as he was asked a question about the Russian president.

"The fact that he killed Prigozhin - at least that's the information we all have, not any other kind - that also speaks to his rationality, and about the fact that he is weak," Zelenskiy said.
