Iran says the United States will pay the price for its plan to relocate its embassy from Tel Aviv to Jerusalem al-Quds.
President Donald Trump formally recognized Jerusalem al-Quds as Israel's "capital" on December 6 and announced plans to move the US embassy to the occupied holy city.
"This is one of the United States' very wrong policies, for which it will pay the price in the future," Foreign Ministry spokesman Bahram Qassemi told reporters during a weekly news briefing in Tehran on Monday.
"With the mindlessness which we see in American decisions, there is need for serious action in the Islamic world," the official added.
The remarks come amid outrage over Trump’s globally condemned decision last month to recognize Jerusalem al-Quds as the capital of the Israeli regime.
