U.S. companies not the only ones responding to US sanctions on Iran

(Reuters) – Iranian officials accused Germany, Britain and the United Arab Emirates on Monday of refusing to refuel Iranian passenger planes in response to tougher U.S. sanctions over its nuclear programme.

A growing number of oil companies, trading houses and other international companies have stopped doing business with Iran this year amid a U.S. drive to isolate Tehran and international efforts to impose tougher sanctions.
