Soldiers in Mali have detained the country's president, as well as the prime minister and other top officials in an apparent coup attempt.
President Ibrahim Boubacar Keïta and PM Boubou Cissé are being held at a military camp near the capital Bamako.
Earlier, the mutinying soldiers took control of the Kati camp.
There has been anger among troops about pay and over a continuing conflict with jihadists - as well as widespread discontent with President Keïta.
Tuesday's mutiny and arrests have sparked international condemnation.
The Economic Community of West African States (Ecowas), a regional bloc that has been mediating talks between President Keïta and opposition groups, has called for the immediate release of all officials.
In a statement , it also said its 15 member states had agreed to close their borders with Mali, suspend all financial flows to the country, and eject Mali from all of Ecowas' decision-making bodies.
