CAIRO, Sept. 11 (Xinhua) -- An Egyptian court sentenced on Wednesday 11 prominent figures of the currently-outlawed Muslim Brotherhood group, including the group's top chief, to life sentence in jail on charges of spying for foreign organizations, official news agency MENA reported.

Life sentence in Egypt is 25 years in jail.

Among the defendants are the Brotherhood's guide Mohamed Badie, tycoon businessman Khairat el Shaater, former Speaker of the Parliament Saad el Katatny, Vice Chairman of the group's Freedom and Justice party Essam el Eryan and the party's General Secretary Mohamed el Beltagi.

Other 17 Brotherhood's members were handed lengthy jail terms ranged from 7-10 years in prison in the same cases.

Meanwhile, six Islamists were acquitted. Charges against former president Mohamed Morsi were dropped due to his death.

The defendants have been convicted of spying with foreign organizations and leaking classified national security information.

They were also found guilty of working with armed groups inside and outside Egypt with the aim to conduct terrorist operations at home.

Morsi was ousted by the military in July 2013 in response to mass protests against his one-year rule and his Brotherhood group, which was later blacklisted as a terrorist organization.
