At a memorial in Moscow, US ambassador Lynne Tracy and British ambassador Nigel Casey were seen paying their condolences.
Vladimir Putin is thought to have ordered Navalny’s assassination, according to his associates. According to prison officials, he experienced “sudden death syndrome”.
Events for the campaigner have resulted in the arrest of almost 400 Russians.
Images from the Solovetsky Stone, a memorial to political repression that has grown to be a significant location for memorials for the 47-year-old Navalny, showed a growing mound of flowers left for the veteran.
The US embassy in Moscow posted on social media, “Today at the Solovetsky Stone we mourn the death of Alexei Navalny and other victims of political repression in Russia.”
“We offer our sincere condolences to the family, associates, and friends of Alexei Navalny. His fortitude serves as an encouraging model. We pay tribute to his memories,” the embassy posted.
