The US Monitor site, reported that the Egyptian ports and airports have been put on high alert after warnings of infiltration by foreign fighters fleeing Syria and Iraq after they joined and fought with extremist groups there, such as mercenaries of Jabhat al-Nasra and Ahrar al-Sham.
The website pointed out that Egyptian officials are concerned enough about these extremist elements and worked to order the security forces to strengthen precautionary measures to regulate the entry of foreign nationals.
The Egyptian website said Egyptian President Abdel Fattah al-Sisi gave this issue a high priority at the recent Munich security conference.
In his speech, al-Sisi asked, "who brought foreign fighters to the Arab countries, and who supports them?" He called on the international community to intensify efforts to reveal the identity of the financial supporters of extremists.
Al-Sisi noted that foreigners had been found among the extremists killed in anti-terrorism operations in Egypt and stressed the importance of non-intervention in the affairs of other countries.
Egypt has seen a number of deadly attacks by religious extremists in recent years. The Sinai peninsula has suffered unrest since the January 25 Revolution.
