Russian opposition leader Alexei Navalny is reportedly in a coma Thursday after falling ill during a flight, which made an emergency landing in Omsk.
Navalny, 44, started feeling unwell while on a return flight to Moscow from the Siberian city of Tomsk, his spokeswoman Kira Yarmysh, said on Twitter. The plane later made an urgent landing in Omsk, she added. He only drank black tea in an airport cafe before takeoff, Yarmysh told Russian radio station Echo of Moscow. "We assume that Alexey was poisoned with something mixed into the tea. It was the only thing that he drank in the morning. Doctors say the toxin was absorbed faster through the hot liquid," Yarmysh tweeted.
