Witnesses say soldiers at a major military barracks rampaged, shot into the air and looted shops in Burkina Faso's second largest city.
Witnesses in Bobo-Dioulasso also said Wednesday that soldiers beat and wounded some residents overnight. Witnesses say soldiers set fire to their barracks' food storehouse.
The incidents are the latest in a string of episodes of unrest in the impoverished West African nation. Earlier this week, soldiers near the capital and in the north shot into the air.
The reports come just over a month after a mutiny that threatened President Blaise Compaore's 24-year rule. Compaore dissolved the government and removed the country's security chiefs but stayed in power.
Teachers also last month launched strikes for better pay and thousands of students joined in support.
