The leadership of the Islamic Revolutionary Guard Corps (IRGC), the elite unit of Iran's armed forces, will be one of the main targets if the US decides to launch a large-scale strike on Iran, sources said, CNN reports.

Such a scenario is being considered by Washington if diplomacy or a limited US strike on Iran does not force the country to abandon its nuclear program.

A large-scale US attack would include a series of simultaneous strikes on Iran's most important military and state facilities, including the IRGC leadership, CNN notes.
