CAIRO — The liberation of seven kidnapped Egyptian soldiers on May 22 in northern Sinai raised several questions about the security vacuum along the Egyptian border with Israel and Palestine.
The Egyptian border with Israel is nearly 256 kilometers long (159 miles) — 270 km (168 miles), if its border with Gaza is included. There was a heavy presence of Egyptian troops and aircraft in Sinai before the soldiers were released, despite the Camp David Accords and the Egypt-Israel peace treaty signed in 1979 stipulating that no Egyptian soldiers are allowed within 20 km to 40 km of the Sinai-Israel border, while 750 Egyptian police officers are allowed.
