US Vice President Joe Biden said on Wednesday that the United States would take action against Iran if long-range ballistic missile tests Tehran said it carried out were confirmed.

"I want to reiterate, as I know people still doubt, if in fact they break the (nuclear) deal, we will act," Biden said during a visit to Israel and the Palestinian territories.

"All their conventional activity outside the deal, which is still beyond the deal, we will and are attempting to act wherever we can find it."

Iran fired two more long-range ballistic missiles on Wednesday as it continued military tests in defiance of US sanctions and fresh warnings from Washington.

Coming just weeks after the implementation of Iran's historic nuclear deal with world powers, this week's multiple missile tests were described by Iran's powerful Revolutionary Guards as a show of force in the face of US pressure.

After similar tests on Tuesday, Washington warned it could raise the issue with the UN Security Council and take further action after US sanctions were imposed in connection with Iran's missile program in January.

The hard-fought deal, which saw international sanctions lifted in exchange for curbs on Iran's nuclear ambitions, did not extend to its missile program.
Biden spoke after meeting Israeli Prime Minister Benjamin Netanyahu, who forcefully opposed the nuclear accord with Iran.

General Amir Ali Hajizadeh, who heads the Iranian Revolutionary Guards' aerospace wing, said the longer-range missiles tested would be capable of hitting the Zionist entity.
