Tunisian members of parliament attend a ceremony to sign the new constitution at the National Constituent Assembly on January 27, 2014. Tunisia's leaders signed the new constitution adopted by lawmakers during the night, a key goal of the revolution three years ago that touched off the Arab Spring. The historic document, seen as one of the most modern in the Arab world, was signed by outgoing Islamist premier Ali Larayedh, Speaker Mustapha Ben Jaafar, and President Moncef Marzouki during a ceremony at the National Constituent Assembly.
