American and British officials met Thursday with opponents of the Iran nuclear deal. They hope to ease fears about the agreement.
In Washington, U.S. Secretary of State John Kerry met with Saudi Foreign Minister al-Jubeir. The Saudi government has expressed concern about the deal.
Afterward, Mr. al-Jubeir warned Iran not to cause trouble in the Middle East region.
In Jerusalem, British Foreign Secretary Philip Hammond and Prime Minister Benjamin Netanyahu debated the deal.
Mr. Netanyahu said the Jewish state would have preferred that Tehran change its behavior before an easing of the economic restrictions against it. He also said it is hard to understand why the agreement does not deal with Iran's call for the destruction of Israel.
