Major Pierre Buyoya (Tutsi) overthrew Bagaza in 1987, suspended the constitution and dissolved political parties. He reinstated military rule by a Military Committee for National Salvation (CSMN). Anti-Tutsi ethnic propaganda disseminated by the remnants of the 1972 UBU, which had re-organized as PALIPEHUTU in 1981, led to killings of Tutsi peasants in the northern communes of Ntega and Marangara in August 1988. The government put the death toll at 5,000; some international NGOs believed this understated the deaths.
