The European Union will most likely include Iran's Islamic Revolutionary Guard Corps on its list of terrorist organisations, the bloc's foreign policy chief Kaja Kallas said on Thursday ahead of a foreign affairs ministers council.
"We are putting new sanctions on Iran and I also expect we will list the Iranian Revolutionary Guard Corps as a terrorist list," she said.
Iran has launched a bloody crackdown on nationwide protests that has left thousands dead. At least 6,373 people have been killed in the protests, activists said.
US President Donald Trump has threatened to potentially launch a military strike against it as a result.
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.
