Egypt has identified seven suspects, including one Egyptian, in the killing of 16 border guards last month that triggered the biggest security sweep along its frontier with Israel in decades, the interior minister said.

The attack on August 5, the worst since Egypt's 1973 war with its Jewish neighbor, underlined how lax policing in the region has emboldened Islamist militants to step up attacks on Egyptian security forces and the Israeli border.

Lawlessness in Sinai deepened after the overthrow of Hosni Mubarak last year and his successor as president, Mohamed Mursi, has vowed to restore order, reports Reuters.

"The security apparatus succeeded in identifying the perpetrators of the incident that killed Egyptian soldiers in Rafah," Interior Minister Ahmed Gamal El-Din told state-owned al-Akhbar.

He told the daily newspaper that the Egyptian suspect belonged to a dormant local jihadi cell but did not mention the nationalities of the other suspects or say if any of the seven had been detained.

Gamal said security forces were still trying to root out members of "disparate" militant groups, some of whom espoused the "takfiri" doctrine, which sees modern society as godless and therefore to be avoided, or attacked.

A complex relationship between the hardline Islamist groups, security forces and local Bedouin tribes hostile to the Cairo government complicates efforts to pacify the region.

It also makes it harder to verify reports of the security mission in the isolated region and the local response.
