Oslo - Tunisia's National Dialogue Quartet won the Nobel Peace Prize on Friday for its contribution to building democracy after the Jasmine Revolution in 2011, the Nobel Committee said.
The EU hailed themediators on Friday, saying they had shown North Africa and Middle East a democratic path out of turmoil.
"The Nobel Peace Prize to the National Dialogue Quartet in Tunisia shows the way out of the crises in the region: national unity and democracy," EU foreign policy chief Federica Mogherini tweeted.
Since Tunisia's Jasmine Revolution in 2011 triggered the Arab Spring, the EU has stepped up support to the North African nation, giving aid and political backing and initiating trade talks.
The EU's top officials also visited Tunis earlier this year to back the fight against a growing Islamist militant threat after a deadly attack in a museum in the capital.
