On July 26, Niger's presidential guard ousted and detained President Mohamed Bazoum. The guard's commander, Gen. Abdourahmane Tchiani, proclaimed himself interim leader and the president of the caretaker National Council for the Safeguard of the Homeland.
On July 31, ECOWAS condemned the coup, suspended financial aid to the country, and gave Niger's coup leaders one week to reinstate the detained president, or the community would use "all measures," including military, to restore order in the African nation.
Several European countries have also suspended aid to Niger and evacuated citizens.
