No media source currently available 0:00 0:02:00 0:00 The Kremlin has made multiple, strenuous denials: of having a secret chemical-weapons program; of having ordered intelligence agents to poison Navalny; and of the Novichok poisoning of former Russian military intelligence officer Sergei Skripal and his daughter in England in March 2018. A British woman who accidentally came into contact with the nerve agent died that July. Navalny spent nearly five months in treatment and recuperation in Germany before flying back on January 17 to Moscow, where he was immediately arrested. Before being ordered to serve 30 days in pretrial detention, he called on his supporters to take to the streets, which they did a week later, in the largest political protests that Russia has seen in years.
