The Nobel Peace Prize was on Friday awarded to human rights champions Ales Bialiatski of Belarus, Russia's Memorial group and Ukraine's Center for Civil Liberties for their work to document war crimes and rights abuses.
The committee called for the release of Bialiatski, who has been jailed since 2021 in Belarus, and insisted its prize was not directed at Russian President Vladimir Putin, who launched an invasion of Ukraine in February.
"This prize is not addressing President Putin ... except that his government ... is representing an authoritarian government that is suppressing human rights activists," Reiss-Andersen said.
Last year, the Peace Prize crowned two champions of freedom of the press, Philippine journalist Maria Ressa and her Russian colleague Dmitry Muratov.
The prize comes with a gold medal, a diploma and a prize sum of 10 million Swedish kronor (about $900,000).
The award will be presented at a formal ceremony in Oslo on December 10, the anniversary of the 1896 death of the prizes' creator, Swedish inventor and philanthropist Alfred Nobel.
Reiss-Andersen said she hoped Bialiatski would be able to attend.
The Peace Prize is the only Nobel awarded in Oslo, with the other disciplines announced in Stockholm.
On Thursday, French author Annie Ernaux, known for her deceptively simple novels drawing on personal experience of class and gender, won the Nobel Literature Prize.
She is the 17th woman to get the nod out of 119 literature laureates since 1901.
The Nobel season winds up Monday with the Nobel Economics Prize.
