A well-known Ugandan opposition figure appeared in a military court Wednesday days after he was reported missing in neighboring Kenya, and denied a charge of seeking military support from abroad to destabilize Uganda’s military forces.

The arrest of a Ugandan opposition figure in Kenya was carried out with Nairobi's knowledge, a Ugandan government spokesperson told AFP Friday.

Uganda’s Minister of Information, Communications Technology, and National Guidance, Chris Baryomunsi, has revealed intricate details about Kenya’s involvement in the arrest of Ugandan opposition leader Kizza Besigye.

Kenya's government said it was investigating how a prominent Ugandan opposition leader was spirited out of Nairobi this week, amid growing criticism that it had failed to protect foreign dissidents on its soil.

Kizza Besigye, a prominent critic of Ugandan President Yoweri Museveni, appeared in a military court Wednesday after being reported missing in Kenya.

Kizza Besigye, a former presidential candidate, went missing over the weekend as he visited the Kenyan capital, reappearing days later in military custody back in Uganda.

Besigye was arrested in Kenya and taken across the border to a Ugandan military jail, according to his wife, Winnie Byanyima, head of the U.N. HIV/AIDS program.
