Detail shows how afraid Putin was of Alexei Navalny. US President Joe Biden became even clearer: “Putin is responsible,” he said on Friday in the White House.

US analyst David Sanger told CNN that Navalny's alleged death is in line with mysterious deaths in Russia. Since the beginning of the war in Ukraine, leading figures from the military, politics and business have died unexpectedly again and again, Sanger said. The question arises as to whether Putin's system was really directly involved in an assassination or whether Navalny died as a result of his imprisonment.
