On February 22, 1972 a faction loyal to Ange Diawara attempted a coup against President Marien Ngouabi. Joachim Yhombi-Opango was instrumental in ending the coup. The musician Franklin Boukaka was killed in the coup, as was former Minister Élie Théophile Itsihou. After more than a year of evading capture Diawara was ambushed and killed in April 1973 by forces loyal to Ngouabi.
