"I'm no longer afraid to speak in public, I want to fight against extremism, I come here for that," says Diallo, 18.
"I like this place because I see my friends, we play football, it's really a welcoming environment. I meet plenty of interesting people here, people who I believe will change our country someday," he says.
A national action plan has been developed to fight the radicalization of youth with a survey among young people who may have been receptive to the extremist rhetoric in the past.
A network of young mentors has been created to encourage dialogue, promote citizenship and the role of youth in social and economic issues.
Young people like Salek, Mariem and Diallo relish the opportunity to become a positive force for their country. Youth centres, like the one in Nouakchott, offer them a chance to shape their future and be part of the solution rather than the problem.
