Egyptian President Muhammad Morsi has fired the country's intelligence chief, Murad Muwafi, and the governor of Northern Sinai.
In a major shake-up, Morsi also asked Defense Minister Hussein Tantawi to replace the commander of the military police, a force that has been heavily used since the ouster 18 months ago of Hosni Mubarak.
The changes followed the killing on August 5 of 16 soldiers at a post in Sinai along the border with Israel and the Gaza Strip.
