The peace talk negotiators suffered symptoms of suspected poisoning after a meeting in Kyiv earlier this month, people familiar with the matter said.

Following the meeting in the Ukrainian capital, Mr. Abramovich, who has shuttled between Moscow, Lviv, and other negotiating venues, as well as at least two senior members of the Ukrainian team developed symptoms that included red eyes, constant and painful tearing, and peeling skin on their faces and hands, the people said.

It would be recalled that Abramovich was one of the people suggested for mediating the conflict between Ukraine and Russia. The Russian billionaire has lost many of his assets to the ongoing war between the two countries including the seizing of his club by the Uk government.
