The rebellion in Bouaké, a city of half a million inhabitants, 350km north of the economic capital Abidjan, comes five months after a similar revolt, when thousands of soldiers left their barracks to demand back pay and benefits.
Unrest linked to the mutiny was then witnessed in cities across the country, including in Abidjan, where gunfire rang out at the defence ministry after soldiers entered the city’s military headquarters.
At the time, the government agreed to take into account the soldiers’ demands concerning bonus payments and improvement of living and working conditions.
