An Egyptian presidential candidate has been detained at a military prison, just three days after his announcement that he would contest the current president at the upcoming elections.

General Sami Anan, believed his arrest was politically motivated, and Egyptian President Abdel Fattah el-Sisi was obstructing any chance for genuine presidential elections.

The army said Anan had not obtained their approval to run, and accused him of seeking to divide the armed forces and citizens of Egypt.
