'Secretary of State Condoleezza Rice warned Iran on Thursday that the United States will not back down in the face of Iranian threats against Israel. Iran answered hours later with another round of missile tests.
'Iranian state television reported Thursday that the missiles fired Wednesday and again overnight, demonstrated that the country can defend itself against an attack by Israel or the United States. The weapons included missiles launched from naval ships in the Persian Gulf, along with torpedoes and surface-to-surface missiles, the broadcast said.'
