World leaders reacted harshly Saturday to President Trump's executive order suspending immigration and visas for citizens from certain countries with majority Muslim populations. Iran, one of the targeted nations, suggested it would limit issuing visas to American tourists. Trump on Friday suspended all refugee admissions to the U.S. for four months and banned the entry of Syrian refugees indefinitely pending a security review meant to ensure terrorists cannot slip through vetting. Trump also issued a 90-day ban on all entry to the U.S. from seven Muslim-majority countries with terrorism concerns, including Syria. The official IRNA news agency Saturday carried a statement by the Iranian foreign ministry that says Iran will resort to "counteraction" to Trump's executive order. "Iran, to defend the dignity of the great Iranian nation, will implement the principle of reciprocity until the removal of the insulting restriction against Iranian nationals," the statement reads. "It will apply corresponding legal, consular and political actions."

The two countries have had no diplomatic relations since 1979 when militants stormed the U.S. embassy. Iranian Foreign Minister Javad Zarif issued a series of tweets in response to President Trump's order, saying the move would be "a great gift to extremists and their supporters." He explained that statement further, tweeting: "Collective discrimination aids terrorist recruitment by deepening fault-lines exploited by extremist demagogues to swell their ranks."

A follow-up tweet promised a reciprocal response: "While respecting Americans & differentiating between them & hostile U.S. policies, Iran will take reciprocal measures to protect citizens."



Nicola Sturgeon, first minister of Scotland, retweeted Trudeau, seconding his invitation: "#WelcometoScotland too."
