An Egyptian emergency court sentenced five Muslim Brotherhood members to prison on Saturday on charges of money laundering and funding an illegal group, dpa reported.
The Supreme State Criminal Security Court sentenced Ossama Mohamed Suleiman, the only one of the five in police custody, to three years in jail.
The rest, including one Saudi national, were convicted to five to eight years in absentia.
The ruling cannot be appealed.
The charges are based on a law passed in 2002, and are considered difficult to prove.
The accused were among 32 Muslim Brotherhood leaders and members arrested - the rest of whom were later released.
Though illegally banned in Egypt, the Brotherhood are largely tolerated in Egypt and run as independents in parliamentary elections. The group failed to secure seats in November's poll, though it was the second largest bloc in the previous term.
