As Pakistan positioned itself as a diplomatic conduit between Tehran and Washington, it quietly allowed Iranian military aircraft to park on its airfields, potentially shielding them from American airstrikes, according to CBS citing sources

Iran also sent civilian aircraft to park in neighboring Afghanistan. It was not clear if military aircraft were among those flights, two of the officials told CBS News.  A senior Pakistan official rejected the claims involving Nur Khan Air Base, telling CBS News, that "Nur Khan base is right in the heart of [the] city, a large fleet of aircrafts parked there can't be hidden from [the] public eye."
