The pressure’s on: New economic sanctions have been approved by Canada and the 27-nation European Union as part of an international effort to get Iran to resume talks about its nuclear program. The U.N. Security Council imposed economic restrictions on Iran in early June, but with these measures the E.U. and Canada join the U.S. in instituting more strict controls. Tehran threatened retaliation, claiming the U.S. is forcing the issue. "Anybody who participates in the U.S. scenario will be considered a hostile country," said Iranian President Mahmoud Ahmadinejad on Sunday. British Foreign Secretary William Hague was undaunted, saying, “I hope Iran takes from this message that European nations are open to negotiations about the nuclear program, but if they don't respond, we will intensify the pressure."
