Ghasemi said the Lebanese people support Hezbollah, which "defends the territorial integrity of Lebanon and fights terrorism." Iran is a key supporter of Hezbollah. Britain's move will make being a member of, or inviting support for, Hezbollah a criminal offense in the U.K., carrying a sentence of up to 10 years in prison. Until now, only the military wing of the Lebanon-based group has been outlawed in Britain, but not it's political arm.
The U.S. also accuses the group of destabilizing the region.
