Sudan's general prosecutor has barred media from reporting news related to the detention of a top opposition leader who was arrested for criticizing the government's security policy in war-torn Darfur.

Yasser Mohammed's order on Monday relates to the detention of 78-year-old opposition leader Sadiq al-Mahdi, leader of the Ummah party.

Al-Mahdi was whisked away from his home and later transferred to Kober prison. He faces accusations of breaching domestic security and threatening the constitution.

Mohammed said the ban is aimed at avoiding "obstruction of justice or influencing the due process of law."

Al-Mahdi was Sudan's last democratically elected prime minister and was removed from office after the 1989 coup by current President Omar Bashir.
