The American Associated Press revealed satellite images it said appeared to show the largest construction project in decades at a secret Israeli nuclear facility as part of the undeclared nuclear weapons program.

The agency noted that the photos show a hole the size of a football field indicating the possibility that the building will consist of several layers, adding that the building is located meters away from an old nuclear reactor in the Negev desert, near the city of Dimona.

The facility is Israel's largest nuclear construction project and is home to decades-old underground laboratories that process spent reactor rods to obtain weapons-grade plutonium for Israel's nuclear bomb program.

According to the agency, the reason for this construction is still unclear, and the Israeli government has not responded to the questions directed by the Associated Press about the type of work practiced inside this facility.

Iran's program

The disclosure of this construction comes at a time when Israel, led by Prime Minister Benjamin Netanyahu, is criticizing Iran's nuclear program, which is still under the supervision of United Nations inspectors, unlike its program, which prompted many voices in the world to demand that Israel disclose the details of its program.

For his part, the Executive Director of the Arms Control Association in Washington called on the Israeli government to disclose what it is doing in this secret nuclear weapons facility.

In light of the nuclear ambiguity policy pursued by Israel, it neither confirms nor denies the possession of atomic weapons, and Tel Aviv has not joined the Treaty on the Non-Proliferation of Nuclear Weapons, which is a historic international agreement aimed at stopping the spread of nuclear weapons.

Israel began secretly building the nuclear site in the late 1950s, with covert assistance from the French government, in an empty desert near Dimona (90 km south of Jerusalem).

Israel concealed the military purpose of the site for years from the United States of America, its main ally now, and even referred to it as a textile factory.
