Burkina Faso’s President Roch Marc Kabore said the summit’s context was “marked by the persistence of terrorist attacks.”
In a report on June 24, the U.S. State Department said attacks in the region had increased 250 percent since 2018.

The multinational Takouba task force is an expanded group of special forces which would target militants and help train national special forces.
It is expected to start operations in the summer with about 100 Estonians and French personnel. Some 60 Czechs will join by end of year and 150 Swedes in 2021.
Italian Prime Minister Giuseppe Conte could confirm Italian interest in the task force during the summit.
The United States mostly provides military support and intelligence.
