Kizza Besigye, a longtime rival of Ugandan President Yoweri Museveni, disappeared on that Saturday while visiting the country for a book launch by Kenyan politician Martha Karua. He reappeared several days later at a military court in the Ugandan capital of Kampala, charged with various terrorism offenses including the illegal possession of firearms.

In July, 36 members of Besigye’s Forum for Democratic Change—one of Uganda’s biggest opposition parties—including one individual who held refugee status in Kenya, were deported from Kenya and charged with terrorism in Kampala.
