Netanyahu added that Jerusalem shares its security concerns with both Cairo authorities and Washington, and that Israel was "taking action" on its side of the border to thwart any threat.
"I hope that the importance of maintaining peace is understood by all parties in Egypt. I think this message has been sent to the Egyptians so very clear by the United States," he added.
Defense Minister Barak, on his part, echoed Netanyahu's concerns and confirmed that Israel had accepted the deployment of reinforcements of the Egyptian army in Sinai in order to improve safety.
With the approval of Israel, Egyptian tanks came in mid-August in northern Sinai.
Meanwhile, Israel's security forces declared a high state of alert ahead of Rosh Hashana weekend, with forces deployed nation wide, and especially in the southern sector.
