Report: Iranian site hit in Israeli attack in October 2024 is being rebuilt

An Iranian site that Israel bombed as part of an October 2024 strike is being rebuilt, according to a report by an international security organization.

The report from the Institute for Science and International Security, published Monday, says that Taleghan 2, formerly a site where nuclear weapons were developed, has seen significant construction over the past year.

The site was one of several hit in Israel’s hours-long strike on Iranian defense batteries and drone and ballistic missile manufacturing and launch sites. The strikes were in retaliation for an Iranian ballistic missile barrage targeting Israel weeks earlier, and came some eight months before the 12-day war between the two countries in June 2025.

The construction at Taleghan 2 began in May, a few weeks before the June war, and by September, several new arched structures had been built at the site, the report said. The arches may enable the buildings to be turned into bunkers. The site was not hit in the June war.

The report added that “a blast mitigation feature” had been added to multiple buildings at the site and that construction is still taking place at the site.

It is unclear whether the site is being rebuilt for nuclear weapons development, the report said, but added, “it is deeply concerning that construction is occurring at a former [late 1990s-2003 crash nuclear weapons program, codenamed the] AMAD plan nuclear weapons development site, raising considerable questions as to the true purpose of the facilities there.”
