WASHINGTON (Reuters) - The United States supports Europe's move to initiate the dispute mechanism in Iran's nuclear deal, the U.S. top envoy for Iran told Reuters on Tuesday, but would like to see Europeans join Washington in its efforts to diplomatically isolate Tehran.

France, Britain and Germany formally triggered the dispute mechanism in Iran's nuclear deal, the strongest step the Europeans have taken so far to enforce an agreement that requires Iran to curb its nuclear program.
