Alexei Navalny, a top Russian opposition leader, was poisoned last month with the same nerve agent that was used on former Russian double agent Sergei Skripal and his daughter in 2018 in the United Kingdom, according to the German government.
In a statement Wednesday, the German government said that Navalny, who is currently being treated in Berlin, was poisoned with the chemical nerve agent Novichok in an attack that is suspected to have been ordered by Moscow.
Navalny first fell ill on a plane in Siberia last month and has since been in an induced coma. Russia has denied poisoning Navalny, though it has often used such tactics in the past against opposition figures.
The German government said that Chancellor Angela Merkel and several top officials met to discuss the poisoning and that Berlin “condemns this attack in the strongest possible terms” and urges Moscow to “explain itself.”
Moscow first sparked international backlash after the 2018 poisoning of Skripal and his daughter in Salisbury, England, with Novichok in an attack widely viewed as revenge against Skripal for his past work for the United Kingdom’s Secret Intelligence Service. Several sanctions were levied against Russian officials over the poisoning, and more than 150 diplomats across Europe and the U.S. were expelled.
Navalny, considered the unofficial leader of the Russian opposition and a top critic of President Vladimir Putin, is currently receiving treatment at the Charité-Universitätsmedizin hospital in Berlin. It is the second time Navalny is believed to have been poisoned, though the first incident was officially ruled an allergic reaction.
Russian officials had initially prevented him from leaving the country but allowed him and his wife to go to Germany after a flood of international criticism.
Bipartisan lawmakers in Washington have torn into Moscow over the poisoning, with Sen. Marco Rubio (R-Fla.), the acting chairman of the Senate Intelligence Committee, saying the suspected poisoning was “at least the 31st assassination attempt against a Putin opponent/defector,” and Sen. Chris Murphy (D-Md.), a member of the Senate Foreign Relations Committee, calling the incident “awful news.”
“It goes without saying that you oppose Putin at your own peril and people like Mr. Navalny are on the right side of history. As always, the price for standing up for freedom comes at a heavy cost,” said Sen. Lindsey Graham (R-S.C.), adding that opposition figures in Russia “have my admiration and total support.”
President Trump closed the Russian Consulate in Seattle and expelled 48 Russian diplomats in the U.S. and 12 Russian intelligence officials based at the United Nations after the 2018 poisoning of Skripal and his daughter, though experts say Navalny’s poisoning may be harder to punish given that it happened in Russia.
