Three Americans accused of being involved in last month’s coup attempt in Congo appeared in a military court in the country’s capital, Kinshasa, on Friday, along with dozens of other defendants who were lined up on plastic chairs before the judge on the first day of the hearing.

The proceedings before the open-air military court were broadcast live on the local television channel.

Six people were killed during the botched coup attempt led by the little-known opposition figure Christian Malanga last month that targeted the presidential palace and a close ally of President Felix Tshisekedi.

Malanga was fatally shot for resisting arrest soon after live-streaming the attack on his social media, the Congolese army said.

The defendants face a number of charges, many punishable by death, including terrorism, murder and criminal association.

The court said there were 53 names on the list, but the names of Malanga and one other person were removed after death certificates were produced.

Malanga’s 21-year-old son Marcel Malanga, who is a U.S. citizen, and two other Americans are on trial for their alleged role in the attack. All three requested an interpreter to translate the proceedings from French to English.
