Iran fired missiles suspected of having of a range of 1,240 miles -- enough to reach Israel or U.S. bases in the region -- and said the tests were successes.
It was the third series of missile tests by Tehran, which had a secret nuclear facility unveiled last week and has talks with the permanent members of the U.N. Security Council and Germany this week about its nuclear program.
Iran says its nuclear program is for peaceful purposes but many Western countries fear it may be a precursor to Tehran developing a nuclear weapon.
The Iranian leadership, particularly President Mahmoud Ahmadinejad, has been openly hostile to Israel.
Tests over the past few days included Monday's firing of the Shahab-3 rocket, which is believed to have a range of 1,240 miles. Two classes of missiles with less range were fired Sunday.
Even before the Monday tests, U.S. officials said they had the international support to impose "severe additional sanctions" on Tehran. However, Security Council members Russia and China have been successful in the past in keeping tough penalties from being levied. It is unknown if the revelation of a secret nuclear facility would change that stance.
