The unity government suffered a partial collapse in 1995. The continuing violence, along with appointing of local government officials who were almost exclusively RPF Tutsi, caused serious disagreement between Kagame and senior Hutu government members, including prime minister Faustin Twagiramungu and interior minister Seth Sendashonga. Twagiramungu resigned in August, and Kagame fired Sendashonga and three others the next day. Pasteur Bizimungu remained president but the makeup of the new government was predominantly RPF Tutsi loyal to Kagame. Twagiramungu and Sendashonga moved abroad to form a new opposition party shortly after leaving the government. Sendashonga, who had also spoken out about the need for punishing killings by rogue RPF soldiers, moved to Kenya. Having survived an attempt on his life in 1996, he was assassinated in Nairobi in May 1998, when a UN vehicle in which he was travelling was fired upon. Many observers believe Kagame ordered the killing; as Caplan noted: "the RPF denied any responsibility, which no one other than RPF partisans believed".
