Deputy national security advisor Ben Rhodes made the comments to reporters accompanying Barack Obama on his visit to Saudi Arabia, during which the US president will be seeking to assure Saudi officials that Washington has not changed its policy on Iran, AFP reported.

“We will be making clear that even as we are pursuing the nuclear agreement with the Iranians, our concern about other Iranian behaviour in the region — its support for (Syrian President Bashar al-) Assad, its support for (Lebanon’s) Hezbollah, its destabilising actions in Yemen and the Gulf — that those concerns remain constant,” said Rhodes.

Saudi Arabia, long wary of the Iranian regime’s regional ambitions, views a November deal between world powers and the Iranian regime over its nuclear programme as a risky venture that could embolden Tehran.
