Iran is investigating potential Israeli infiltration following a reported bombing on June 16 that targeted a highly classified underground facility in Tehran where President Masoud Pezeshkian was attending a high-level security meeting.

According to Fars News Agency, which is closely aligned with the Revolutionary Guard, six explosives struck key access and ventilation points at the site during an emergency session of the Supreme National Security Council.

The blasts reportedly injured President Pezeshkian’s leg, but he and others managed to escape through an emergency tunnel. While the report has yet to be independently verified, the incident is now at the center of Iranian claims of foreign sabotage, with suspicion pointed squarely at Israel.

Social media footage from the 12-day conflict showed repeated missile strikes against a mountainous area in northwest Tehran. Fars now suggests those strikes were part of an operation aimed at crippling the underground complex believed to be sheltering Iran’s top leadership at the time.

The report alleges that all six entry and exit routes to the facility were blocked in the assault, and power as well as ventilation systems were knocked offline. Despite this, Pezeshkian reportedly reached safety.

The Supreme National Security Council, second in power only to Supreme Leader Ayatollah Ali Khamenei, was in session at the time of the attack. Pezeshkian last week accused Israel of attempting to assassinate him an allegation Israeli Defense Minister Yoav Gallant dismissed, saying regime change was never an objective of Israel’s military operation.

The strike came as part of a broader Israeli campaign that decimated the upper ranks of Iran’s Revolutionary Guard and military command within the opening hours of conflict. Iranian officials later admitted they were caught off guard, with a paralyzed chain of command during the first 24 hours.

While Israel has acknowledged that Ayatollah Khamenei was a target, officials claimed they lost track of him after he was relocated to a heavily secured and isolated site.

Intelligence experts are now raising questions over how Israeli forces obtained such precise details about Iran’s leadership movements and the locations of its most secretive facilities.

The war began on June 13 when Israel launched a surprise offensive against suspected nuclear and military sites, citing the need to prevent Iran from acquiring atomic weapons. Tehran denies the accusations, insisting its uranium enrichment is strictly for peaceful energy use.

On June 22, U.S. forces joined the offensive, with coordinated air and missile strikes on three nuclear installations inside Iran. President Donald Trump later said the strikes “obliterated” the targets, although some American intelligence agencies have expressed caution over the actual damage assessment.
