Egypt President sacks officials after Sinai attacks
Egyptian President Mohammed Mursi has sacked the country's intelligence chief and the governor of the country's North Sinai province.
Hours earlier, the Egyptian military launched an offensive in the region against suspected Islamist militants which it says has killed 20 people.
The campaign comes after militants killed 16 Egyptian border guards in the area on Sunday.
Jeremy Bowen reports on how security breaches in the area have far reaching implications.
