US whistleblower Edward Snowden, Pakistani schoolgirl Malala Yousafzai and Russian President Vladimir Putin are among the nominees for this year's Nobel Peace Prize, as the Nobel Institute announced a record 278 candidates.
"The number of nominations increases almost every year, which shows a growing interest in the prize," the head of the institute, Geir Lundestad, said.
The Nobel committee convened on Tuesday for the first time this year to examine the candidate list and will announce the laureate in Oslo on October 10. As usual, the committee refused to reveal the identity of any of the nominees, but Lundestad said that 47 of the 278 candidates were organisations.
Even though the list is kept secret for at least 50 years, the sponsors can choose to reveal the name of their nominee.
Putin is thought to be on the list, since Russian figures proposed his name in October. The former KGB agent is credited with averting a US attack against Syria by suggesting the chemical weapons arsenal belonging to the regime of Bashar al-Assad be put under international control.
Being nominated for the Nobel Peace Prize is relatively easy, since thousands of people can suggest candidates: lawmakers and ministers, university professors and former laureates.
At their first meeting, the five committee members themselves can add more names to the list.
The committee insists that being nominated does not imply an endorsement on its part.
Another name on the list is Snowden, the former contractor at the US National Security Agency who has been provided asylum in Russia and is accused in his country of disclosing a large number of classified documents regarding a US global surveillance programme. Others with a similar profile, such as WikiLeaks founder Julian Assange, are also known to be on the list.
The 16-year-old Yousafzai, seriously wounded when she was shot in the head by a Taliban gunman at point blank range for promoting girls' education in her country, is again known to be nominated, after being considered one of the favourites last year.
However, the 2013 prize went to the Organisation for the Prohibition of Chemical Weapons, involved to this day in the dismantling of the Syrian chemical weapons arsenal.
Other names known to be on the list include jailed Belarussian rights activist Ales Belyatski and Denis Mukwege, a pioneering doctor who founded a clinic for rape victims in the Democratic Republic of Congo, both nominated in the past.
Kristian Berg Harpviken, director of the Peace Research Institute Oslo (Prio) and one of the few experts to speculate openly on the winner, said his favourite for this year was Pope Francis for his efforts to redistribute wealth in the world.
Asked about the situation in Ukraine, Berg Harpviken said it was difficult to point out an individual or an organisation that could play a major role in the region in the months to come.
"The dramatic situation in which Ukraine finds itself could influence the Nobel committee's thoughts, but at this stage I don't see any clear candidates standing out," he said.
