British TV presenter David Attenborough, the World Health Organization and Belarusian activist Svetlana Tikhanovskaya are among the nominees for this year's Nobel Peace Prize after being supported by Norwegian lawmakers, Reuters reports.

Also among the candidates for the award were Greta Thunberg, Pope Francis, Myanmar's Government of National Unity, formed by opponents of last year's coup, and Tuvalu's Foreign Minister Simon Kofe, Reuters reported.

Thousands of people, from members of parliaments from around the world to former winners, are eligible to nominate candidates.

Every year since 2014, with the exception of 2019, Norwegian legislators have nominated a possible Peace Prize winner, including Maria Ressa, one of last year's two laureates.

The Norwegian Nobel Committee, which decides who wins the prize, does not comment on the nominations. Attenborough, 95, is best known for his iconic television series illustrating the natural world.

Another Green Party spokesperson nominated Greta Thunberg of Sweden, whose journey from teenage activist to global climate leader has made her a frequent Nobel Prize nominee in recent years, along with the Fridays For Future movement she founded.

Belarusian activist Svyatlana Tikhanovskaya has been nominated for the second year in a row for her brave, tireless and peaceful work in the name of democracy and freedom in her country.

Other candidates revealed by Norwegian lawmakers include Russian activist Alexei Navalny, the International Criminal Court in The Hague, WikiLeaks and Chelsea Manning, NATO, the charity CARE, Iranian human rights activist Masih Alinejad and the Arctic Council.

Nominations do not require the approval of the Nobel Committee. The 2022 winner will be announced in October.
