Egypt steps up security on border as Israeli offensive in Gaza nears

Egypt has sent about 40 tanks and armoured personnel carriers to northeastern Sinai within the past two weeks as part of a series of measures to bolster security on its border with Gaza, two Egyptian security sources said.

The deployment took place ahead of the expansion of Israeli military operations around Gaza's southern city of Rafah, where much of its population has sought safety, sharpening Egyptian fears that Palestinians could be forced en masse out of the enclave.

Israeli warplanes struck Rafah, which adjoins the border, on Friday and Prime Minister Benjamin Netanyahu ordered the military to prepare to evacuate the displaced people.

Since the war between Israel and Hamas erupted on October 7, Egypt constructed a concrete border wall that reaches six metres into the ground and is topped with barbed wire. It has also built berms and enhanced surveillance at border posts, the security sources said.

Last month Egypt's state information service detailed some of the measures it had taken on its border in response to Israeli suggestions that Hamas had obtained weapons smuggled from Egypt. Three lines of barriers made any overground or underground smuggling impossible, it said.

Images shared with Reuters by the Sinai Foundation for Human Rights, an independent group, appear to show the installation of the wall in December, with several berms running behind it.

Later pictures, which the group said were taken in early February, appear to show three vertical layers of coiled barbed wire being installed on top of the wall. Reuters was not able to independently verify the images.

Satellite images from January and December also show some new constructions along the 13km border close to Rafah and the extension of a wall to the sea's edge at its northern end.

Egyptian and Israeli authorities did not respond to requests for comment.

The new measures come after an expansion of security in northern Sinai as Egypt's military consolidated its grip against an insurgency that escalated a decade ago.

Well before the current war in Gaza broke out, Egypt said it had destroyed tunnels through which smuggling to Gaza had previously flourished, and had cleared a buffer zone close to the border.

On the approach to the Rafah Crossing with Gaza, the remains of razed houses can been seen along with miles of concrete walls that have been built parallel to the sea and near roads close to the border.

Egypt and Israel have been at peace for more than four decades and in recent years have extended ties through Israeli exports of natural gas and security coordination around their shared border and the Gaza Strip.

Egypt has framed its opposition to the displacement of Palestinians from Gaza as part of wider Arab rejection of any repeat of what Palestinians mourn as the "Nakba", or "catastrophe", when some 700,000 fled or were forced from their homes in the war surrounding Israel's creation in 1948.
