BEIRUT -- Iran said Sunday that it was cutting off oil exports to France and Britain in a pre-emptive strike against European economic sanctions, while top U.S. and British officials warned against a military attack on Iran's disputed nuclear program.
Iran's retaliatory oil ban was the latest instance of high-stakes brinkmanship surrounding Tehran's nuclear ambitions. Iran says its program is solely for peaceful purposes, but the U.S. and many of its allies suspect the goal is to develop weapons.
