A spokesperson for Roman Abramovich has confirmed the Russian oligarch was suspected to have been poisoned earlier this month after meeting to discuss peace talks with Ukrainian negotiators.
They would not confirm who else was targeted or what the source of the attack was.
Earlier, a report from the Wall Street Journal claimed three people who attended negotiations in Kyiv had experienced red eyes, constant and painful tearing, and peeling skin on their faces and hands.
Abramovich is said to be ok now as the incident happened several weeks ago, and he will continue with negotiations alongside those from Ukraine in an attempt to end the war.
Those close to Abramovich say he has been involved in several meetings, and is only working on behalf of himself after it was claimed he was asked to help.
