The provisional figure was confirmed by rebel-appointed authorities on Thursday evening, after earlier reports said more than 20 children were feared dead. The fire, whose cause is unknown, also destroyed some 300 houses in the area, according to officials.
Survivors have been taken to nearby hospitals, and footage from the scene shows children lying on hospital floors in pain. Pictures circulating on social media show young children lying motionless on the ground. A witness quoted by Reuters said the fire had been put out by afternoon but smoke was still rising from rubble and corrugated metal.
Bukavu, the capital of South Kivu province and one of DR Congo's most crowded hillside cities, was captured by M23 rebels in February last year.
In Kinshasa, the national government released a statement on X without specifying casualty numbers. The Ministry of National Education and New Citizenship expressed deep sorrow over the deadly fire, noting that several lives had been lost and many injured, with the toll remaining provisional. The minister offered condolences, affirmed solidarity with families, and ordered assessments of affected schools to ensure learning continuity.
The tragedy follows a similar fire in Kinshasa last weekend, where residents died in a stampede at a wedding banquet hall. In response, the government has ordered strict safety measures and deployed teams nationwide to enforce standards at public gathering places.
