Israeli Prime Minister Benjamin Netanyahu said that no direct communication has taken place between him and Egyptian President Mohamed Mursi since his election, adding that Mursi is yet to refer to the Jewish state by name.
In an interview with Jerusalem Post, on Sunday, Netanyahu said that several interactions have taken place between his government and Egypt's new administration - but were mainly military based and none of them with Egypt's newly-elected Islamist president himself.
The Israeli PM insisted that his government remains concerned with events in Sinai, adding that order in Sinai is important for Egypt as it is for Israel.
He made it clear that Egypt is responsible for restoring order in Sinai.
Netanyahu insisted that keeping the peace accord with Israel is among his government's priorities.
"I think that Egypt must declare its stance on its serious commitment to the peace treaty. We have announced our serious commitment to the treaty and I hope they do as well."
Meanwhile, in an interview with Reuters, Mursi, without saying the word "Israel", insisted that no one should be concerned with the military operation taking place in Sinai.
The operation began after militants attacked a military checkpoint at the Rafah border killing 16 Egyptian police and army men in a failed attempt to cross the barbed wire into Israel.
