Nobel Peace Prize awarded to Denis Mukwege and Nadia Murad for helping end sexual violence The awards went to two people working to end sexual violence as a weapon of war.

LONDON -- Denis Mukwege and Nadia Murad have each won the 2018 Nobel Peace Prize for their work to end the use of sexual violence as a weapon of war in armed conflict.

The Norwegian Nobel Committee declared that "each of them in their own way have helped to give greater visibility to wartime sexual violence so that the perpetrators can be held accountable for their actions."

Mukwege "has spent large parts of his adult life helping victims of sexual violence," said the chair of the Norwegian Nobel Committee, Ms. Berit Reiss-Andersen.

As a gynecologist, "Mukwege and his staff have treated thousands of patients who have fallen victim to such assaults. Most of the abuses have been committed in the context of a long-lasting civil war that has cost the lives of more than six million Congolese."

In the announcement, Reiss-Andersen also told the story of fellow winner Nadia Murad, a member of the Yazidi minority in northern Iraq, who as a captive of ISIS was "repeatedly subjected to rape and other abuses." After three months of being held hostage, she managed to escape, and has since spoken out about her ordeal.

The Nobel Committee commended them both for having "put their personal security at risk by courageously combating war crimes and seeking justice for the victims."

#MeToo and war crimes

Gender has been a key issue for the Nobel Committee this year. The Nobel Prize in Literature was canceled because of a scandal centered on the influential cultural figure Jean-Claude Arnault, who was convicted of rape on Oct. 1.

However, Frances Arnold became the fifth woman in history to win the Nobel Prize in chemistry, and Donna Strickland became the first female winner of the Nobel Prize in physics in 55 years.

When asked if the #MeToo movement had inspired the Nobel Committee's choice, Reiss-Anderson said #MeToo and war crimes are not quite the same things.

But they do have in common that it is important to see the suffering of women, to see the abuses. And to achieve that it is also important that women leave [behind] the concept of shame and speak up."

Prize still has 'tremendous influence'

The North Korean leader Kim-Jong Un and South Korean President Moon Jae-in had been the favorites for the award for their work on denuclearization. The bookies Sky Bet had priced the pair at 4/7, while U.S. President Donald Trump had been touted as the second favorite at 4/1.

In recent decades the academy has often come under scrutiny for a number of controversial awards. Henrik Urdal, the director of the Peace Research Institute Oslo, told ABC News that Nobel Prize winners former U.S. President Barack Obama and Myanmar Prime Minister Aung San Suu Kyi were two such laureates.

"I think Barack Obama is a case where they jumped too early," he said. "When it comes to Aung San Suu Kyi, she was awarded for something I think is worthy of the Nobel Peace Prize. But she hasn't lived up to the expectations afterward."

Obama was given the prize after less than a year in office, and Aung San Suu Kyi has been accused of severe human rights violations since becoming prime minister.

The selection process is often fraught with dilemmas, and this year would have been no different.

The committee voters "are trying to vet the candidates for background," Urdal said. "But there is no guarantee whatsoever that they don't do something ridiculous and something that's in opposition to the idea of the prize at a later point in life."

Daniel Hogsta, the campaign coordinator for last year's winners, the International Campaign to Abolish Nuclear Weapons, told ABC News that the biggest change that comes from winning the award is the increased media attention.

The award "hasn't fundamentally changed the priorities of the work, but it elevated everything to a different level," he said. "It's been difficult in some aspects –- we're flooded with requests for comment, appearances and interviews. But generally it's been a huge positive."

Urdal believes the Nobel Peace Prize still carries a "tremendous influence."

"The attention that it brings every year is not getting any less," he added. "They are able to award the prize for very different kinds of achievements. If all the winners were agreeable to everyone I don't think the prize would be equally important."
