Leading Kenyan lawyer and former Justice Minister Martha Karua has been blocked from entering Uganda and ordered to return home, according to the Uganda Law Society.
Karua had just arrived at the Entebbe airport to join a team defending her Ugandan lawyer colleague Erias Lukwago, with whom they have been representing detained opposition leader Kizza Besigye, who is on trial for treason.
Lukwago was himself charged with a treason-related offence last week, and his bail hearing had been due on Monday.
On her return to the Kenyan capital, Nairobi, she said denying her entry had been "unlawful and politically motivated", reports the Daily Nation news site.
She said that as a citizen of the East African Community, she should have the right to enter another member country, such as Uganda.
The site also quotes her as saying she had been told she was persona non grata in Uganda.
Ugandan authorities have not given a reason for blocking Karua, although Kenya's Law Society President Charles Kanjama, who had travelled with her, was allowed in.
