A Suez military court has sentenced four leaders from the banned Muslim Brotherhood group to life in prison in absentia, on charges related to using violence and terrorising citizens, MENA reported.

The court ordered 15 to 25 years in prison for each of the defendants.

An anonymous source told the state news agency that the convicted included Ahmed Mahmoud, Mohamed Shabana and Abdel Rahman Ibrahim, all well-known figures from the Freedom and Justice Party, the political arm of the Muslim Brotherhood during their one-year rule.

The military prosecution charged the defendants of joining an outlawed group, inciting violence, using force and possessing weapons in the case, related to 2014 clashes in Egypt's coastal city of Suez.

Since Morsi's ouster, courts have issued mass death sentences in a number of cases against Morsi loyalists, most of which were either revoked or are being appealed.

Brotherhood supreme guide Badie was sentenced to death in two other cases, with one overturned by an appeals court and the second rejected by the Grand Mufti, who has to approve all death sentences in Egypt.
