Tanzanian authorities have detained dozens of people and deployed heavy security forces across Dar es Salaam ahead of anti-government protests planned for Tuesday, July 7. The demonstrations, organised largely by young activists, coincide with the 72nd anniversary of the ruling Chama Cha Mapinduzi (CCM) party and centre on demands for democratic reforms and the release of opposition leader Tundu Lissu, who faces treason charges after calling for electoral reforms. The crackdown follows disputed elections last October in which President Samia Suluhu Hassan claimed 97 percent of the vote amid an opposition boycott, with subsequent unrest that rights groups say left thousands dead — far above the government's official toll of 518.
