Protesters against President Pierre Nkurunziza's decision to run for a third term in Bujumbura, Burundi, wear masks to hide their identity as street demonstrations continue after a failed military coup. Materials used range from grass and leaves to bin liners and old fabric to plastic bags, while woolly hats make impromptu balaclavas. The protesters say Nkurunziza's desire to stay in office violates the east African state’s constitution and a peace accord that ended an ethnically charged civil war in 2005.
