The U.S. should understand that the rules of the game in war against Iran have changed "before it is too late", Iranian Parliament Speaker Mohammad Baqer Qalibaf said on Sunday, a day after the U.S. struck several Iranian tankers in the Gulf.
"From now on, any attack against Iran's interests and security will receive a faster, heavier and more painful response," he said in a speech published on his Telegram channel.
