CAIRO (Reuters) - Egypt has appointed Major General Khaled Megawer to serve as the head of the country’s military intelligence service, replacing Mohamed al-Shahat, two security sources told Reuters on Sunday.

Egypt’s military and intelligence services play a leading role in top level decision making, taking a more public role since current president Abdel Fattah al-Sisi led the 2013 military overthrow of Egypt’s first freely-elected president, Mohamed Mursi of the Muslim Brotherhood.

The sources did not give a reason for al-Shahat’s dismissal, but Sisi has replaced several high-ranking security officials in the military, interior ministry and the general intelligence service over the last couple of years.

Sisi appointed close ally Major General Abbas Kamel to serve as chief of the country’s General Intelligence Service in June, two weeks after replacing the defense and interior ministers.

Megawer previously served as deputy head of the military intelligence body, Commander of the Second Field Army and Defense Attaché at the Egyptian embassy in Washington.
