U.S .President Barack Obama said Thursday there was "no dispute" that Iran was involved in an alleged terrorist plot against the Saudi ambassador in Washington that was uncovered this week.
"We would not be bringing forward a case unless we knew exactly how to support all the all facts contained in the indictment," Obama told a press conference during a visit by South Korean President Lee Myung-bak.
Obama said he would "take any options off the table in terms of how we operate with Iran," but indicated the United States would continue to pressure Tehran, including pursuing tougher sanctions.
