The Egyptian army has planned military attacks on specific targets in the Gaza Strip in the event that the security situation in the northern Sinai peninsula deteriorates, a senior Egyptian security official told the Ma'an news agency.
The source said that Egyptian reconnaissance planes had photographed the potential targets.
According to intelligence sources, the Egyptian Army would attack from the air.
The plan to attack targets in Gaza is based on the Egyptian assessment that some of the attacks in the northern Sinai, especially in El Arish and in Rafah were carried out by armed Palestinians based in Gaza.
The security source said that the Egyptian Army is specifically targeting the extremist groups in Gaza who are regarded as hostile and it does not view the entire population there in this way.
The recent attack on the intelligence center in Rafah was carried out by the extremist Gaza groups, the source told Ma'an.
Last week Egypt opened the Rafah crossing, its main border with the Gaza Strip after it was closed for a week and-a-half
The terminal had been closed most of the time since the ouster of former Egyptian president Mohamed Morsi on July 3 due to the Egyptian accusation leveled against Hamas of its involvement in terrorist attacks against Egyptian soldiers in Sinai – an allegation the Islamist movement has vehemently denied.
Egypt recently warned of a military response if Hamas or other Palestinian groups try to violate Egyptian security in Sinai.
Foreign Minister Nabil Fahmy told the London-based newspaper al-Hayat there was "tension" in Cairo's relationship with Hamas, an ideological offshoot of Morsi's Muslim Brotherhood. He suggested Hamas was not helping enough to secure the border.
