State TV quoted Rouhani on Tuesday as saying that "if someday, the United States decides to block Iran's oil (exports), no oil will be exported from the Persian Gulf."

Rouhani also pledged that the US wouldn't be able to prevent Iran from exporting its crude oil.

His threat was welcomed by many Iranian officials, including hard-liners such as Gen Qassem Soleimani
, the commander of the Revolutionary Guard's powerful Quds Force.
