TEHRAN, Oct. 15 (Xinhua) -- The U.S. President Donald Trump's recent anti-Iran speech was under the influence of lobbyists from Israel and Saudi Arabia, Iran's Parliament Speaker Ali Larijani said on Sunday.

It was clear that the Zionist regime of Israel and some countries like Saudi Arabia "have played a major role in "writing" Trump's speech and guiding him," Larijani was quoted as saying by Press TV.

He said that the U.S. president's aggressive rhetoric was aimed to cause commotion and prevent international economic cooperation with Iran.

On Friday, the U.S. president refused to certify Iran's international nuclear deal and accused Tehran of sponsoring terrorism, saying that he would deny Iran's "all paths to a nuclear weapon."

Accordingly, Saudi Arabia and Israel welcomed the new strategy towards Iran announced by Trump.

Iran has insisted that its nuclear energy program is aimed at civilian purposes.
