The US Middle East envoy called the foreign ministers of Saudi Arabia, UAE, Qatar and Iraq to ask them to deliver a message to Iran urging it to lower tensions with Israel following a suspected Israeli air strike on Iran’s embassy in Syria, a source with knowledge of the situation told Reuters.

White House Middle East czar Brett McGurk asked the officials to contact the Iranian foreign minister to convey a message that Iran should de-escalate with Israel, which they did, said the source, who spoke on condition of anonymity.

Iran’s foreign ministry said on Wednesday the foreign ministers of Saudi Arabia, the United Arab Emirates, Qatar and Iraq spoke on the phone with Iran’s foreign minister and discussed regional tensions.

The White House declined to comment.
