Iran vowed on Sunday to close the Strait of Hormuz if the U.S. follows through on President Donald Trump's threat to attack its nuclear power plants.

Trump said on Saturday evening that Iran would have a 48-hour deadline to fully open the strait before the U.S. and Israel start attacking Iranian nuclear power plants.

In response, the Iranian regime said the strait would be “completely closed” if Trump started to strike their power plants, the Associated Press reported.
