Egypt is building a wall and is leveling land near its border with the Gaza Strip ahead of a planned Israeli offensive targeting the border city of Rafah, satellite images analyzed Friday by The Associated Press show.

Egypt, which has not publicly acknowledged the construction, repeatedly has warned Israel not to forcibly expel the over 1 million Palestinians now displaced in Rafah across the border into its territory while it battles the militant group Hamas for a fifth month.

However, the preparations on the Egyptian side of the border in the Sinai Peninsula suggest Cairo is preparing for just that scenario, something that could threatened its 1979 peace deal with Israel that's been a linchpin for regional security.

The Egyptian government did not respond to requests for comment Friday from the AP. The Egyptian Foreign Ministry on Feb. 11 issued a statement warning Israel over its possible Rafah offensive and its “displacement of the Palestinian people.”

The satellite images, taken Thursday by Maxar Technologies, show construction ongoing on the wall, which sits along the Sheikh Zuweid-Rafah Road some 3.5 kilometers (2 miles) west of the border with Gaza. The images show cranes, trucks and what appear to be precast concrete barriers being set up along the road.

Those satellite images correspond to features seen in a video released by the London-based Sinai Foundation for Human Rights on Feb. 12. The video shows a crane lifting concrete walls into place along the road.

Nearby as well, construction crews appear to be leveling and clearing ground for an unknown purpose. That can also be seen in imagery from Planet Labs PBC of the area. The Wall Street Journal, quoting anonymous Egyptian officials, described “an 8-square-mile (20-square-kilometer) walled enclosure” being built in the area that could accommodate over 100,000 people.

Hard-line officials within Israeli Prime Minister Benjamin Netanyahu's government have raised the possibility of pushing Palestinians out of the Gaza Strip, something strongly opposed by Israel's main ally, the United States. The Gaza Strip and the occupied West Bank are lands the Palestinians hope to have for their future state.

The Israeli military referred questions regarding Egypt's construction to Netanyahu's office, which did not immediately respond.

A report by Israel's Intelligence Ministry, drafted just six days after Hamas' Oct. 7 attack from the Gaza Strip that killed 1,200 people and saw over 250 others taken hostage, included a proposal of moving Gaza’s civilian population to tent cities in the northern Sinai, then building permanent cities and an undefined humanitarian corridor.

In the time since, the Israel-Hamas war has laid wide swaths of the seaside enclave to waste and killed more than 28,600 people, mostly women and children, according to the Health Ministry in Gaza.
