The United States unleashed its “toughest ever” sanctions against Iran on Monday, a move that has already sparked mass protests in the oil-rich nation.
The Trump administration reinstated all sanctions removed under the 2015 nuclear deal, targeting both Iran and states that trade with it.
They will hit oil exports, shipping and banks – all core parts of the economy.
Thousands of Iranians chanting “Death to America” rallied on Sunday, rejecting calls for talks.
Iranian President Hassan Rouhani has vowed to sell his country’s oil and break the sanctions.
The military was also quoted as saying it would hold air defence drills on Monday and Tuesday to prove the country’s capabilities.
The demonstrations took place on the 39th anniversary of the occupation of the US embassy in Tehran, which led to four decades of mutual hostility.
Before travelling to a campaign rally for the US mid-term elections, President Donald Trump said Iran was already struggling under his administration’s policies.
“The Iran sanctions are very strong. They are the strongest sanctions we’ve ever imposed. And we’ll see what happens with Iran, but they’re not doing very well, I can tell you.”
Washington re-imposed the sanctions after Mr Trump in May pulled out of a 2015 accord aimed at curbing Iran’s nuclear ambitions.
Washington also says it wants to stop what it calls Tehran’s “malign” activities including cyber attacks, ballistic missile tests, and support for terror groups and militias in the Middle East.
“We are working diligently to make sure we support the Iranian people and that we direct our activity towards ensuring that the Islamic Republic of Iran’s malign behaviour is changed,” US Secretary of State, Mike Pompeo, told Fox News Sunday.
“That’s the goal, that’s the mission, and that’s what we will achieve on behalf of the president.”
