The 2020 Nobel Peace Prize has been awarded to the United Nations World Food Programme (WFP) for its efforts to combat hunger.

The Norwegian Nobel Committee said the WFP had acted "as a driving force in efforts to prevent the use of hunger as a weapon of war and conflict".

The prize is worth 10m Swedish krona ($1.1m; £872,600).

The winner was announced at the Norwegian Nobel Institute in Oslo.

A WFP spokesman said it was a "proud moment".

The WFP estimates it helps about 97 million people a year, in 88 countries.

"With this year's award, the [Committee] wishes to turn the eyes of the world to the millions of people who suffer from or face the threat of hunger," said Norwegian Nobel Committee chairwoman Berit Reiss-Andersen.

"The World Food Programme plays a key role in multilateral cooperation in making food security an instrument of peace."

Some 211 individuals and 107 organisations were nominated for the prize this year. Under the Nobel Foundation's rules, nomination shortlists are not allowed to be published for 50 years, and the organisation says any speculation ahead of the announcement is "sheer guesswork".

The World Health Organization and climate activist Greta Thunberg were among the favourites for this year's award.

Who are previous Nobel Peace Prize winners?

The Nobel Peace Prize last year went to Ethiopian Prime Minister Abiy Ahmed, whose peace deal with Eritrea ended a 20-year military stalemate following their 1998-2000 border war.

Former US President Barack Obama won the prize in 2009, for "his extraordinary efforts to strengthen international diplomacy and co-operation between peoples".

Other notable winners include former US President Jimmy Carter (2002); child education activist Malala Yousafzai (shared 2014); the European Union (2012); the United Nations and its secretary-general at the time, Kofi Annan, (shared 2001); and Mother Teresa (1979).

What's the background?

The Nobel Prize is one of the world's most important awards.

It was started in accordance with the will of Swedish inventor Alfred Nobel, with the first award handed out in 1901.

Nobel Prizes are awarded in several categories to people "who have conferred the greatest benefit to humankind" in the previous 12 months.

The recipient of each Nobel Prize receives three things:

• A Nobel diploma, each of which is a unique work of art
• A Nobel medal
• A cash prize, which is split between winners when there is more than one. They have to deliver a lecture to receive the money

There have been some years when the prize has not been awarded - mostly during the two world wars.

Nobel Foundation rules state if nobody deserves the prize in a particular category, it is not awarded and its prize money is kept for the following year.
