US Vice-President Kamala Harris has blamed the Kremlin for Alexei Navalny's reported death, as tributes pour in from US lawmakers.
Speaking in Munich, Ms Harris said that Russia is responsible "whatever the story they tell".
Russia's prison service said Navalny, 47, one of the country's most significant opposition figures, died in an Arctic Circle jail on Friday.
Several other US government figures and lawmakers have expressed their concern.
Navalny was serving a 19-year sentence on charges that have widely been condemned as politically motivated. For the past decade, Navalny and his Anti-Corruption Foundation have formed the main domestic opposition to Russian President Vladimir Putin.
In a statement, Russia's prison service said that Navalny "felt unwell" during a walk on Friday at the facility in the Yamalo-Nenets district and "almost immediately lost consciousness".
"The emergency doctors declared the prisoner dead," the statement added. "Cause of death is being established."
Speaking at the Munich Security Conference on Friday, Ms Harris said that the US had yet to confirm the news, but if it was true this was "further sign" of the "brutality" of President Putin.
"Whatever the story they tell, let us be clear, Russia is responsible," she said, adding that "we will have more to say on this later".

Secretary of State Anthony Blinken – who was also at the conference alongside 44 US lawmakers – said that the US will "be talking to many other countries" about Navalny, "especially if these reports bear out to be true".
According to the State Department, Mr Blinken met Navalny's wife Yulia on the sidelines of the conference to express his condolences "if the reports….are true".
Ben Cardin, the chair of the powerful Senate Foreign Relations Committee, issued a statement in which he said Navalny's reported death "is not just a tragedy for the Russian people, but a profound loss felt across the international community".
"The need for the international community to stand in solidarity with those who fight for democracy and human rights could not be more urgent," Mr Cardin added. "As we mourn this loss, we cannot shrink from our collective responsibility to hold accountable those who seek to silence dissent through violence and repression."
House Speaker Mike Johnson called Mr Putin a "vicious dictator" who is "likely directly responsible" for Navalny's reported death.
"If confirmed, this action is emblematic of Putin's global pattern of silencing critics and eliminating opponents out of fear of dissent," he said, calling for "united opposition" against Russia.
Former Vice-President Mike Pence, a long-time Putin critic, said that there was "no room in the Republican Party for apologists for Putin".
Navalny was last seen earlier this week, when he appeared in court hearing via video link. During the hearing, he appeared healthy and was laughing.
"I don't want to hear any condolences," his mother was quoted as saying on Friday. "We saw him in prison on 12th [February], in a meeting. He was alive, healthy and happy."
