Iran is preparing a broader and more forceful response if the United States launches major military strikes include again, possible attacks on facilities in countries in addition to US operations and on beyond the Middle East, Reuters reported, citing unnamed sources.

Tehran is actually pursuing diplomatic efforts, although Iranian officials believe the prospect of those initiatives successful are very low, according to the report.

Three senior Iranian officials and a person familiar with the discussion said Iran’s top military commanders were reviewing plans to expand the list of potential targets. The planning would be directly linked to the United States and consider sites in the United States and consider sites in countries supporting US military operations, as well as possible outside the Middle East.
