Russian billionaire Roman Abramovich and Ukrainian peace negotiators suffered symptoms of suspected poisoning earlier this month after a meeting in Kyiv, the Wall Street Journal reported on Monday, citing people familiar with the matter.
Abramovich, who accepted a Ukrainian request to help negotiate an end to the Russian invasion of Ukraine, and at least two senior members of the Ukrainian team, were affected, the WSJ report said.
