U.S. President Donald Trump's threat to destroy Iran's nuclear facilities is a clear red line and will have severe consequences, the semi-official Fars News Agency reported on Friday.

Any Israeli campaign on Iran without the U.S. support will face severe limitations given the long distance between the two countries.

US President Donald Trump said he envisions a nuclear deal with Iran that would allow the destruction of “whatever we want” in the country including labs, a version of an inspections regime that is likely to be rejected by Tehran.
