The European Union formally adopted an oil embargo against Iran. As it faces more sanctions, Iran is renewing its recent threat about a key oil route.

FOX News Radio's Alastair Wanklyn reports:

One Iranian lawmaker saying Iran might now choke off other nations' oil exports in the Strait of Hormuz, after the European Union today agreed a ban on new Iran oil sales.

(Hague)"I think this will also influence the actions of many other nations."

Including maybe other Iran-oil purchasers Japan and South Africa. That's Britain's Foreign Secretary William Hague.

Just this weekend U.S. aircraft carrier the Abraham Lincoln entered the Strait of Hormuz on what the U.S. Navy calls a routine maneuver.
