Iranian Parliament Speaker Mohammad Bagher Ghalibaf has said that the US should understand that the rules of the game in war against Iran have changed “before it is too late.”

Axar.az reports, citing Iranian media, that Ghalibaf made the remarks a day after the US struck several Iranian tankers in the Gulf.

“The era of proportional responses is over. Just as we defeated the United States in the military and diplomatic arenas, we will defeat it in the economic war,” he said.

Ghalibaf said that strikes on U.S. bases were only the beginning.

“From now on, any attack against Iran’s interests and security will receive a faster, heavier and more painful response,” he said.
