BRUSSELS (AP) — The European Union appeared poised Thursday to sanction Iran’s paramilitary Revolutionary Guard over Tehran’s deadly crackdown on nationwide protests, further squeezing the Islamic Republic as it worries over a threat by U.S. President Donald Trump to potentially launch a military strike against it.

America has moved the USS Abraham Lincoln and several guided-missile destroyers into the Mideast, which can be used to launch attacks from the sea. Iran has kept up its own threats as well, saying it could launch a preemptive strike or broadly target the Mideast, including American military bases and Israel.

It remains unclear what Trump will decide about using force, though he has threatened to use it in response to the killing of peaceful demonstrators and over possible mass executions. At least 6,373 people have been killed in the protests, activists said.

But the move by Europe, long considered, will put new pressure on Iran as its economy already struggles under the weight of international sanctions. Its rial currency fell to a record low of 1.6 million to $1 on Thursday. Economic woes had sparked the protests that broadened into challenging the theocracy before the crackdown.

“This will put them on the same footing with al-Qaida, Hamas, Daesh,” the EU's top diplomat, Kaja Kallas said, using an Arabic acronym for the Islamic State group. “If you act as a terrorist, you should also be treated as a terrorist.”

Iran had no immediate comment, but it has been criticizing Europe in recent days as it considered the move, which follows the U.S. earlier sanctioning the Guard.

By EU law, sanctions require unanimity across the bloc’s 27 nations. That's at times hindered Brussels’ ability to flex its economic clout to crack down on Russia over its invasion of Ukraine.

For Iran, France had objected to listing the Guard as a terrorist organization over fears it would endanger French citizens detained in Iran, as well as diplomatic missions, which provide some of the few communication channels between the Islamic Republic and Europe and its allies. However, the office of President Emmanuel Macron on Wednesday signaled Paris backed the decision.

French Foreign Minister Jean-Noël Barrot said Thursday before the Foreign Affairs Council in Brussels that France supports more sanctions in Iran and the listing “because there can be no impunity for the crimes committed.”

“In Iran, the unbearable repression that has engulfed the peaceful revolt of the Iranian people cannot go unanswered,” he said.
