Iran says it will bar US citizens from entering the country. The announcement comes as a response to Donald Trump's executive order banning immigrants from several predominantly Muslim countries, Iran one of them.

An Iranian Foreign Ministry statement reads, "The US decision to restrict travel for Muslims to the US, even if for a temporary period of three months, is an obvious insult to the Islamic world and in particular to the great nation of Iran. Despite the claims of combating terrorism and keeping American people safe, it will be recorded in history as a big gift to extremists and their supporters."

Iran's ban will remain as long as Trump's does, the statement said.
