Deposed Egyptian president Mohamed Morsi is to be tried on accusations that he handed documents relating to national security to Qatar, the state prosecutor has announced.

Morsi is already facing the death penalty in several trials, and his supporters, including top ranking members of the Muslim Brotherhood, have been the target of a deadly crackdown by authorities since his ousting in July 2013.

No date has yet been set for the new trial facing Morsi, who is accused of providing the sensitive documents to the energy-rich Gulf state during his single year of turbulent rule.

Relations between Qatar, a key supporter of Morsi's government, and Egypt have been tense since mid-2013, when then-army chief Abdel Fattah el-Sisi toppled Morsi.
