U.S. accuses Pakistan of sheltering Iranian military aircraft at Nur Khan airbase during Operation Sindoor

Pakistan’s problem here is not just the planes. It’s the contradiction. Islamabad spent the spring presenting itself as the go-between that helped pull Washington and Tehran back from a wider war. Now U.S. officials are saying that, around the same time, Pakistan also let Iranian military aircraft sit at one of its most important airbases. That turns a mediator story into a double-game story — or at least a trust problem. ### What is the actual allegation? The core claim is pretty specific. U.S. officials told CBS News that, days after President Donald Trump announced a ceasefire with Iran in early April, Tehran sent multiple aircraft to Pakistan Air Force Base Nur Khan outside Rawalpindi. One of them was said to be an Iranian Air Force RC-130, a reconnaissance variant of the C-130. The implication is not that Pakistan joined Iran’s war effort outright, but that it gave Iranian military assets a safer parking spot while the risk of renewed U.S. strikes still hung over the region.

It is one of Pakistan’s key military and VIP air facilities, near Islamabad and Rawalpindi, and it handles sensitive transport and logistics. That matters because parking aircraft there is not routine in the casual sense — it signals state-level permission and oversight. It also matters symbolically because Nur Khan has become a stage for Pakistan’s diplomacy; it hosted the U.S. and Iranian delegations that came to Islamabad for follow-up talks after the ceasefire. (cbsnews.com) ### Did this happen during fighting or after it? That timing is the whole dispute. The U.S. side frames the aircraft movements as part of Iran’s effort to protect remaining aviation assets from possible American strikes, even after the ceasefire announcement, because everyone knew the truce could collapse. Pakistan’s side says the planes arrived during the ceasefire period, not active hostilities, and were there for diplomatic, logistical, and security support tied to the Islamabad talks. (indianexpress.com) Same planes, same base — completely different story about what their presence meant. ### What is Pakistan saying back? Pakistan is not denying that Iranian aircraft were at Nur Khan in some form. Its officials are denying the sinister version. The line from Islamabad is basically: yes, a few Iranian aircraft remained there, but they were connected to mediation and follow-on visits, and U.S. aircraft and security teams also used the base during the same peace process. One senior Pakistani official pushed back by saying a large fleet at Nur Khan could not have been hidden because the base sits in the middle of a populated urban area.

Pakistan had won unusual visibility by helping broker the April ceasefire and then hosting U.S.-Iran talks in Islamabad. That role let Islamabad look useful to Washington, close to Tehran, and regionally indispensable all at once. But if U.S. officials now believe Pakistan quietly gave Iran’s military breathing room, then the mediator image starts to look less like neutral bridge-building and more like hedging — keeping every side close without fully choosing one.

The allegation rests on unnamed U.S. officials speaking to CBS News, while Pakistan’s rebuttal also comes through officials rather than a detailed public release with flight logs, satellite imagery, or tail-number records. So the public case is still incomplete. But the specificity of the RC-130 claim is what gives the story weight, because that is not the kind of detail people usually float casually in a diplomatic spat. (aljazeera.com) ### Why is “Operation Sindoor” in the background? Because Nur Khan was already a loaded site before this story broke. The base drew attention after being damaged in India’s 2025 Operation Sindoor, and it later reappeared as the arrival point for Vice President JD Vance and Iranian officials heading into Islamabad talks. So this one airbase now sits at the intersection of India-Pakistan tensions, U.S.-Iran diplomacy, and Pakistan’s own attempt to sell itself as a pivotal regional broker. (cbsnews.com) That makes every aircraft parked there politically louder than it would be anywhere else. ### Bottom line The immediate issue is not whether a few Iranian aircraft touched down in Pakistan. Pakistan’s own side more or less concedes some did. The real fight is over intent. If they were there for talks, Islamabad looks useful. If they were there to shield Iranian military assets, Islamabad looks duplicitous. And right now, that distinction is exactly what Washington seems to be testing. (cbsnews.com) (indianexpress.com)
