Saudi Arabia welcomed the new U.S. policy towards Iran and said lifting sanctions had allowed Iran to develop its ballistic missile program and step up its support for militant groups, state news agency SPA reported on Friday.

The kingdom said Iran took advantage of additional financial revenues to support for the Lebanese Shi'ite movement Hezbollah and the Houthi group in Yemen.

Donald Trump said on Friday that he will decertify the Iran nuclear deal, and announced new sanctions on the Revolutionary Guard.

The United Arab Emirates meanwhile said that it fully supported the new U.S. policy towards Iran and it renewed its commitment to work with Washington to counter Iran's support of extremism, the state news agency WAM reported.

"The UAE announces its full support to the new U.S. strategy to deal with the Iranian policies undermining security and stability," WAM said on its twitter account.

Bahrain has also announced it welcomed the shift in U.S. policy on Iran's nuclear and ballistic missile programs and its support for extremist groups in the Middle East.

Israeli Prime Minister Benjamin Netanyahu immediately congratulated Trump for his "courageous decision" not to recertify the nuclear deal with Iran.
