The German government said on Monday two more laboratories have independently confirmed that Kremlin critic Alexei Navalny was poisoned with the Soviet-style nerve agent Novichok and called on Russia to cooperate.
Special labs in Sweden and France have confirmed the initial results from Germany, government spokesman Steffen Seibert said in a statement.
"We renew the call for Russia to explain itself on the events. We are in close contact with our European partners on further steps," he added.
