"Egypt has deployed forces beyond the permitted quota, expanded port facilities, and extended runways at airports," The Jerusalem Post quoted the source as saying, adding that these actions violate the peace agreement between the two countries.
Regarding the entry of Egyptian forces beyond the permitted quota, security officials emphasised that "such actions are reversible – it is not a problem to pull tanks back."
The security source said that Israel is committed to maintaining the peace agreement and will not alter its deployment along the border.
However, the source also added, "Israel will not accept the situation and will not tolerate violations from Cairo."
Israel is currently in discussions with both Cairo and Washington on the matter.
"Washington is responsible for upholding the peace agreement and must ensure it is implemented as written," the source was quoted as saying.
So far, Israel has refrained from commenting on Egypt’s military buildup, aside from a few rare statements.
In February, Israel’s Ambassador to the US Yechiel Leiter said that Egypt’s military buildup in Sinai is "intolerable."
"For a long time, this issue was pushed aside, but it is continuing. This will be a topic we are going to put on the table – very soon and very firmly," the ambassador had said.
