Commenting on a suggestion made by Egyptian presidential advisor Mohamed Saif al-Dawla to amend the Camp David Accord, Israeli Foreign Minister Avigdor Lieberman said that no changes have taken place in the deal.

The treaty, signed between Egypt and Israel in 1979 under former Egyptian President Anwar al-Sadat, forbids Egypt from sending over heavy arms to the Sinai Peninsula.

Meanwhile, following a recent attack on Egypt's Rafah border leading to the death of 16 Egyptian army and police men, Egypt began a security operation in Sinai in an attempt to purge the area from militants and terrorist activities.

Israel granted Egypt's security operation a wary approval as Egypt sent out armored carriers, conscripts, policemen and helicopters to Sinai to arrest armed men and suspects and confiscate arms.

Expressing concerns about the reinforcements sent to the region, Lieberman told ABC, "There is no chance that Israel will agree to any amendments. Egyptians should not delude themselves or others - and not rely on that request".

Egypt's presidential spokesman Yasser Ali said on Thursday that Sinai affairs are primarily an Egyptian national security concern.
