‘A Los Angeles hospital confirmed on Friday that two U.S. women who became ill during a trip to their native Russia, prompting investigations by both countries, were suffering from thallium poisoning.
Cedars-Sinai Medical Center said Marina Kovalevsky and her daughter, Yana, were receiving “appropriate treatment” for thallium poisoning. They have been listed in fair but stable condition. [..]
There has been no official explanation of how or why the two women, who according to family members do not work for either government and have no known political or business ties to Russia, were poisoned.’
