Peskov told reporters that Russian law enforcement would launch an investigation if poisoning was confirmed.
The Kremlin says that a decision to refuse the transfer to Germany of opposition leader Alexei Navalny, who is in a coma in a Siberian hospital with suspected poisoning, is based only on medical grounds.
"This is a question of a purely medical decision," President Vladimir Putin's spokesman, Dmitry Peskov, told journalists on August 21 after Russian doctors said Navalny was not well enough to be moved from the Omsk hospital where he is being treated, RFE/RL reported.
