Also present in Dakar was global singing star Rihanna who vowed on Friday she would "never stop fighting" to get millions of children back in school.
"Rihanna doesn't hide it: she's part of the Illuminati, a branch of Freemasons", Diagne reportedly said.
Ahead of the event, Rihanna tweeted world leaders asking them to commit to funding education in the world's poorest nations, including British leader Theresa May and Australia's Malcolm Turnbull. She called for the U.K.to pledge £380 million ($542 million), Australia to contribute AUD$200 million ($160 million) and France to pitch in €250 million ($312 million) by end of business today.

In 2016, Rihanna was named GPE's first-ever Global Ambassador; her role is to "encourage world leaders and policymakers to boost their support for global education and education in emergencies through GPE".
This is not the first time the pair have met. Macron hosted Rihanna at his presidential palace past year after she challenged him on Twitter to contribute to her efforts to fund education in developing countries, notably in conflict and crisis areas.
Partner countries in the GPE scheme are required to earmark 20 percent of their national budgets for education - a tough goal for developing nations battling jihadists or civil conflicts.
