Authorities in the Democratic Republic of Congo say they thwarted an attempted coup in the capital Kinshasa on Sunday. Armed men attempted to storm the presidential palace, as well as the home of a key lawmaker, in an attempt to overthrow President Félix Tshisekedi’s government. Around 50 people involved in the plot were arrested, including three U.S. citizens. The apparent coup leader, Congolese opposition figure Christian Malanga, died during the attack. Malanga had lived in exile in the United States for over a decade.
