Iran says it's going to ban all U.S. citizens from entering the country. It's a response to the Trump administration's ban on people coming to the U.S. from seven Muslim-majority nations, including Iran.
The ban, part of an executive order signed by President Donald Trump on Friday, bars people from coming to the U.S. for the next 90 days if they're from Iraq, Iran, Syria, Libya, Somalia, Yemen or Sudan.
Iranians have been barred from entering to the U.S. before. President Jimmy Carter blocked them from getting visas during the Iran hostage crisis.
A statement from the Iranian Foreign Ministry said, in part, the U.S. ban is "an obvious insult to the Islamic world and in particular to the great nation of Iran."
But the two-way ban complicates an already complex relationship between the two countries. President Trump has scrutinized the Iran nuclear deal the Obama administration negotiated. But just days before Trump's inauguration, Iranian President Hassan Rouhani said there was little chance the deal would be renegotiated.
There's no word on how long Iran's ban against the U.S. will last or what the terms will be.
