The prosecution official said on Thursday a judge will investigate the report filed last month accusing Mohammed El-Baradei, Nobel Prize laureate and former head of the UN nuclear agency, along with Amr Moussa, former foreign minister and Hamdeen Sabahi, a former presidential candidate, of inciting the overthrow of Egypt's first elected president, Mohammed Morsi.

The official spoke on condition of anonymity in line with government policies.

The accusations were filed by a lawyer during a political crisis over a series of presidential decrees that granted Morsi and the committee drafting the disputed constitution immunity from judicial oversight. Tensions were fed by deadly clashes between pro- and anti-Morsi demonstrators.
