DUBAI, United Arab Emirates (AP) — As U.S. President Donald Trump’s deadline on opening the Strait of Hormuz approaches, Iran on Monday threatened to attack Mideast electrical plants powering American military bases.

The statement from Iran’s paramilitary Revolutionary Guard marks the latest attempt by Tehran to try and explain its attacks on the Gulf Arab countries.

Iranian state television read out the statement on air Monday morning.

“What we have done is to announce our decision that if the power plants are attacked, Iran will retaliate by targeting the power plants of the occupying regime and the power plants of regional countries that supply electricity to US bases, as well as the economic, industrial and energy infrastructures in which Americans have shares,” the statement said, referring to Israel as an “occupying regime.”

It added: “Do not doubt that we will do this.”

Trump warned early Sunday morning that the U.S. will target Iranian power plants in 48 hours if the strait remains effectively closed by Iranian fire on shipping.
