Prime Minister Benjamin Netanyahu requested U.S. Foreign Minister Marco Rubio urge Egypt to cease military expansion in the Sinai Peninsula, citing alleged violations of the 1979 Peace Agreement with Israel, during a meeting in Jerusalem on Monday, September 15th, 2025. Netanyahu presented Rubio with details of these activities, which he characterized as essential breaches of the agreement guaranteed by the United States. These accusations follow reports from earlier in the week detailing alleged Egyptian military infrastructure expansion, including the construction of underground facilities and aircraft runways, according to Axius via MTV Lebanon News. Human Rights Watch reported in March 2021 that between late 2013 and July 2020, the Egyptian army destroyed at least 12,350 buildings in the Sinai. Satellite imagery shared on social media geolocates Israeli military deployments, including Merkava Mk4 tanks and Namer Infantry Fighting Vehicles, near Egypt's border in Zone D of the Camp David Accords' security annex. This zone limits Israeli forces to four infantry battalions and bans heavy armor, tanks, and artillery, indicating potential Israeli violations of the 1979 treaty, according to EGYOSINT. These diplomatic and intelligence developments occur amidst ongoing Israeli Defense Forces (IDF) operations in Gaza. Earlier on September 20th, 2025, an IDF soldier was moderately injured by sniper fire in Gaza City's Sheikh Radwan neighborhood. The IDF has continued operations, including dismantling terror sites and striking targets across Gaza, Khan Yunis, and Rafah. The IDF struck over 100 terror targets in Gaza earlier today, and six additional fatalities were reported in an Israeli attack on Gaza City's Tuffah neighborhood between 10:04 AM and 10:34 AM UTC, contributing to a day's total reported deaths of 51 at that time.
