Revolutionary Guard's aerospace division Commander Gen. Amir Ali Hajizadeh talked to semi-official Fars news agency on Tuesday and said the test was an “important one” and that Iran conducts 40-50 tests per year.

Hajizadeh, said the American outcry “indicates that the test was very important to them.”

Under the 2015 nuclear accord, Iran was urged to cease its testing of ballistic missiles, but the agreement does not forbid such tests.

President Donald Trump withdrew the U.S. from the landmark agreement in May despite Iran's continued compliance. European nations have been working to salvage the agreement, which curbs Iran's uranium enrichment.
