Egypt has built military bases in Sinai "that can only be used for offensive operations, for offensive weapons," Israel's ambassador to the United States, Yechiel Leiter, highlighted on Sunday.
Leiter called it a "clear violation of the peace treaty between Egypt and Israel - after some 45 years."
He also noted that the Israeli government will present Cairo's military buildup in Sinai "very soon."
Leiter first said this in a meeting with American Jewish organizations on January 28, however the recording of this was just shared online by the Conference of Presidents of Major Jewish Organizations in America on Friday, according to the Jewish News Syndicate.
Ten days ago, Egypt released a video showing its army's military capabilities, which includes hundreds of tanks, fighter jets, helicopters and navy vessels.
Last May, retired Lt. Col. Eli Dekel, who has been researching Egypt for 60 years, claimed that Egypt had increased its armored forces by hundreds of tanks.
"I did not find an explanation in the media for why Egypt increased its armored forces by 700 tanks. They call it a cold peace, but that's not what this is," he told Maariv.
The ambassador pointed out the violations in the Sinai Peninsula are "a subject that is bound to come up because it is unacceptable."
He added that the issue has been pushed aside for a long time: "We will put this issue on the table very soon, and in a decisive manner."
This comes after satellite images indicating changes in the deployment of the Egyptian military in the Sinai Peninsula reportedly concerned security coordinators in Israeli border communities.
Egypt-Israel since October 7
In May 2024, Lt. Col. Dekel sought to draw attention to the fact that "since the start of the war, Egypt has been issuing threats to us in one way or another."
"A few days ago, the military academy was inaugurated, attended by President Sisi. The trainees learned what the weak points of the Merkava tank were. Two days before that, the Egyptian army spokesman released an entire propaganda film, in which he said: 'We are preparing our army in case Israel does not listen to our wise advice not to occupy Philadelphi.'"
Dekel also argued that Egypt's role in the October 7 attacks should be examined.
Egypt has kept military presence in the Sinai for a long time in order to stop terrorism spilling over from Gaza and to prevent the proliferation of terror in Egypt proper.
