Easing of Iran sanctions could start in December

In addition to a six-month window for Iran to allow more U.N. access to nuclear sites, sanctions will be eased—notably in the oil, automotive and aviation industries—though not ended.

The agreement is a first step—one that Israel has condemned as a “historic” mistake that effectively accepts Iran as a threshold nuclear weapons state.

Israel has found common cause with Saudi Arabia, which shares concerns about a nuclear-armed Iran and Tehran's growing regional influence.

On his return to Tehran, Iranian Foreign Minister Mohammed Javad Zarif told state television that the country was prepared for quick follow-up negotiations to keep the deal on track.
