A military general who criticized Uganda's longtime president has been charged in a court-martial and remanded to jail.

Gen. David Sejusa was charged Tuesday with being absent without leave, participating in political activities and insubordination.

A lawyer for Sejusa, David Mushabe, described Sejusa as "a prisoner of conscience" who has been targeted for criticizing President Yoweri Museveni as a dictator.

Sejusa's problems started in 2013, when he wrote a letter to the domestic spy chief urging him to investigate allegations of a plot to kill high-ranking government officials seen as being opposed to the political rise of Museveni's son, Brig. Muhoozi Kainerugaba.

Facing likely arrest, Sejusa, who, was traveling in Europe at the time, sought asylum in London. He quietly returned home in Dec. 2014.
