Egypt's Muslim Brotherhood said court verdicts in which ousted President Mohammad Mursi and others were sentenced to death on Tuesday were "null and void."

The group also called for a "popular uprising" on Friday in a statement on its Facebook page.

"The Brotherhood calls on the honorable among this nation to participate in a popular uprising next Friday against the death sentences, detentions, kidnappings, and forced disappearances," the group said.

Egypt court sentenced Mursi and the MB general guide Mohammad Badie to 25 years in jail each in case related to conspiring with foreign groups.

The court still has to decide whether to confirm or commute death sentences it handed down against Mursi and more than 100 others in a separate trial on charges related to their escape from prison during the 2011 uprising that ousted former President Hosni Mubarak.
