Israel hopes the United States will knock out Iran's underground nuclear site Fordow with its superior firepower but may try alone within days while military gains and global opinion allow, two Israeli security sources told Iran International.

Israel hopes the United States will knock out Iran's underground nuclear site Fordow with its superior firepower but may try alone within days while military gains and global opinion allow, two Israeli security sources told Iran International.
The two sources still viewed joint action alongside the United States as the most likely scenario, within 48-72 hours at most.
An attack could be underway as early Friday night, the sources added, but Israel is also weighing going it alone to avoid losing the military advantage it has gained this week.
“In order for us to force Iran into concessions it would otherwise not make, and to bring it back to the negotiating table, this is the only way; we need the US to take action," an Israeli intelligence source told Iran International on condition of anonymity.
"We need Trump to do this within the next two to three days," one source added. "Trump is extremely unpredictable right now though, so anything could happen.”
Buried deep underground, the Fordow nuclear enrichment facility has remained untouched so far in the ongoing Israeli military campaign which appeared to take Iran by surprise in the early hours of last Friday morning.
Window closing
The window of opportunity to knock out the site was closing, the second Israeli security source said, and Israel had been planning for an attack for months.
“Until now the IDF (Israeli military) has opened up the flight path to Iran and the skies are open but that will be for a limited time, it can’t go on indefinitely,” he told Iran International on condition of anonymity.
“Therefore, if America decides to get involved, it has to be a decision made as fast as possible otherwise the opportunity will be missed.”
As the war begins to impact the global economy, including the soaring price of oil, the source said world powers could quickly lose patience with the conflict.
“There are economic issues at stake, so for example if oil prices spike, then these countries could be involved due to their own economic interests. So in general, America has to take this opportunity within 48-72 hours.”
The reach and strength of Israel's bombers are more limited compared to their American peers, making an attack on Fordow by Israeli forces alone more complex.
“Israel doesn’t have the heavy B-52 capabilities to drop a 14-ton bomb to penetrate the heart of the Iranian atomic sites that have to be destroyed,” the security source said.
Israel’s F-15s travel nearly 2,000 kilometers with far smaller payloads of around 400 kilograms, the source added. "Do the math. America could do that mission within a few days, but for us, it would be a much longer, more complex operation."

Destroying the Fordow enrichment facility requires a US military asset never been used in war, according to a report in the Wall Street Journal.
Known as the Massive Ordnance Penetrator, the GBU-57 is designed to tear through 200 feet of mountain rock before exploding. The United States has around 20, the newspaper reported, delivered via B-2 stealth bombers.
In the White House on Wednesday, Trump maintained studied ambiguity. “I may do it. I may not do it. I mean, nobody knows what I’m going to do,” he told reporters.
Iain Overton, the Executive Director of Action on Armed Violence, told Iran International that despite the heavy blows taken, Tehran could opt to fight on.
“Iran may lack parity in conventional military terms, but it possesses a distributed deterrent capability: armed proxies across the region, cyber warfare expertise, and a long-honed ideological machinery that frames death not as loss but as victory," he said.
"If the Ayatollah’s regime interprets US involvement as existential, it will not capitulate. It will escalate.”

The Taliban’s General Directorate of Intelligence (GDI) held a high-level internal session on the possible escape of Islamic Revolutionary Guard Corps and al-Qaeda members into Afghanistan, alongside a potential wave of Iranian refugees, Afghanistan International has learned.
Amid the ongoing conflict between Israel and the Islamic Republic, the session outlined several key concerns and scenarios.
IRGC members seeking asylum
Facing potential instability, senior members of the Islamic Revolutionary Guard Corps (IRGC) could flee Iran and seek refuge in Afghanistan. GDI discussed the possibility during the session that such individuals might request protection from the Taliban, according to Afghanistan International’s sources.
Risk of al-Qaeda member relocation
Senior al-Qaeda figures such as Saif al-Adel and Abu Abdulrahman, who are believed to currently reside in Iran, may attempt to escape the country amid instability. GDI has asked the Taliban leadership for guidance on how to respond if they attempt to enter Afghanistan—whether to accept them, place them under surveillance, or reject their entry altogether. This discussion was part of the internal analysis obtained by Afghanistan International.
In 2021, then–US Secretary of State Mike Pompeo accused Iran of harboring al-Qaeda leaders. US and UN intelligence agencies later confirmed that Saif al-Adel was residing in Iran and is now considered al-Qaeda’s de facto leader. In 2024, the US State Department reaffirmed that Iran continues to provide safe haven to senior al-Qaeda operatives.
Preparedness for influx of Iranian refugees
GDI has posed a critical question: Can Afghanistan absorb a possible wave of Iranian refugees? The session called for urgent contingency planning to evaluate national capacity, political risks, and humanitarian consequences.
Armed Revolutionary Guard forces have taken control of Iran’s state broadcaster compound in Tehran following an Israeli airstrike that disrupted operations and heightened fears among employees, sources told Iran International on Wednesday.
Access to the state-run broadcaster’s complex, located in northern Tehran’s Jam-e-Jam area, is now tightly restricted, with only cleared personnel allowed to enter.


Armed Revolutionary Guard forces have taken control of Iran’s state broadcaster compound in Tehran following an Israeli airstrike on Monday that disrupted operations and heightened fears among employees, sources told Iran International on Wednesday.
Access to the state-run broadcaster’s complex, located in northern Tehran’s Jam-e-Jam area, is now tightly restricted, with only cleared personnel allowed to enter.
Witnesses report heightened security checks and a significant armed presence. The compound has effectively turned into a restricted zone, one staff member said, speaking on condition of anonymity.
Sources told Iran International that some senior editorial staff and reporters left the building hours before the strike after receiving warning signals. Others, citing safety concerns, have refused to return.
“There is deep anxiety among middle managers and staff — not only about their security but also their livelihoods,” said one source.
The strike on Monday — part of a wider escalation between Israel and Iran — caused technical disruptions inside the broadcaster as dust and smoke engulfed the studio of the live broadcast, with videos showing fire coming from the glass building.
The extent of physical damage remains unclear, but sources say programming has been affected and internal operations significantly curtailed.
Iranian officials have condemned the attack as a violation of international law. “Even during wartime, media facilities are protected under international humanitarian rules,” one senior official told local press, referring to Article 79 of Protocol I of the Geneva Conventions, which classifies journalists as civilians so long as they do not engage in hostilities.
IRIB President Peyman Jebelli confirmed that the IRINN studio (IRIB’s 24-hour news network) had been “destroyed,” but vowed that programming would gradually resume.
“Despite the damage, our core broadcasts — including the 20:30 news bulletin — will return,” Jebelli said in remarks broadcast on Wednesday. He himself was reportedly present at the time of the attack but was unharmed.
The targeted structure, known as the Glass Building, is an iconic symbol of Iranian modernist architecture, designed by famed architect Abdol-Aziz Farmanfarmaian in the 1960s. It housed newsrooms and executive offices.
The fourth floor, believed to have suffered the most damage, was home to the news editorial board and the political bureau.
While official casualty figures have not been confirmed, local media reported the deaths of three people, including senior news editor Nima Rajabpour and administrative staff member Masoumeh Azimi.
TV anchor Sahar Emami was engulfed in smoke and debris as she was speaking live on air, with loud booms rocking the studio.
Amid the strike, she told viewers: “The sound you just heard is the sound of the aggressor attacking our homeland, the sound of the aggressor seeking to stifle rightfulness and truth."
The cameras continued to roll before she was forced to abandon the studio.
A group of employees at Iran’s state broadcaster, IRIB, have said they will not return to work following Israel’s recent strike on the organization, according to information received by Iran International.
