What caused the explosion at a nuclear facility in central Iran?

It seems increasingly likely that the 2 July explosion at the Iran Centrifuge Assembly Centre, located near the Natanz Pilot Fuel Enrichment Plant, was the result of sabotage. And, despite initial speculation that it was the result of a cyberattack against critical operational control systems—and thus of a similar vein to the Stuxnet attack that took down multiple centrifuge cascades at Natanz in 2010—the simpler and more plausible explanation is that the explosion was caused by a bomb.

Despite claims of responsibility by a previously unknown group calling itself the Homeland Cheetahs that supposedly comprises disgruntled Iranian former military and security services personnel, it now appears widely accepted that Israel was behind the attack. There has been further speculation that Israel was also behind other curious incidents that have occurred at Iranian facilities in recent weeks—including explosions at the gas storage area near the Khojir missile facility at Parchin, at a medical facility in Tehran, and at a factory south of Tehran—although there is as yet no evidence of foul play in these events.

Multiple media outlets—including the New York Times and the Washington Post—have referenced intelligence officials attributing the Natanz attack to Israel. And while Tehran was slow in apportioning blame, on 7 July it accused Israel of being behind the attack, saying it was ‘a “wake-up call” meant to deter Iran amid advancements in its nuclear program, and … [that] those who planted the explosives had significant insight into the country’s nuclear program’.
