TEHRAN, September 1. /TASS/. Iran considers the US naval blockade an act of military aggression and will respond in kind, Mohammad Bagher Ghalibaf, speaker of the Islamic Republic’s unicameral parliament, the Majlis, said.

"If they tighten the blockade, we will certainly respond militarily, and everyone will lose. If the enemy decides to prevent us from exporting oil from the Persian Gulf, no one will be able to export oil," Ghalibaf said in a video address to Iranians.

In his view, the United States is currently focusing more on the psychological aspect of its economic war against Iran, as a significant portion of the newly announced sanctions had already been imposed before.

Earlier, US President Donald Trump announced the start of an "economic warfare and isolation" against Iran on an unprecedented scale. He also warned that countries whose financial institutions, businesses, airports or state entities support Tehran would face serious economic consequences from the United States.
