OSLO -- The Tunisian National Dialogue Quartet, which helped build democracy in the country after the 2011 revolution, has received the Nobel Peace Prize.

This year's award was collected at a ceremony in the Norwegian capital by members of four organizations, representing unions, industry, trade and human rights.

The Norwegian Nobel Committee cited the group for "its decisive contribution to the building of a pluralistic democracy" after the revolution that overthrew its long-time authoritarian president.

The quartet is made up of four key organizations: the Tunisian General Labor Union; the Tunisian Confederation of Industry, Trade and Handicrafts; the Tunisian Human Rights League; and the Tunisian Order of Lawyers.

The Nobel awards in medicine, physics, chemistry, literature and the Nobel Memorial Prize in economic sciences, are to be presented in Stockholm later Thursday.
