OUAGADOUGOU - Dozens of supporters of the Burkina Faso military coup on Sunday chanted slogans and wrecked furniture as they stormed a Ouagadougou hotel hosting efforts to end the country's post-putsch crisis, an AFP journalist said. The attack came as mediators led by Senegalese President Macky Sall - who also chairs the Economic Community of West African States (ECOWAS) - were due to announce an exit plan Sunday morning for the landlocked west African country from the crisis triggered by Thursday's military coup.
