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.
