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.

Leading Ugandan opposition figure Kizza Besigye appeared in a military court in Kampala on Wednesday after his reported abduction in neighbouring Kenya.

Kenya's government has 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.
