Iran nuclear: Tehran crowds cheer negotiators

Cheering crowds have welcomed home the Iranian negotiators who secured a nuclear deal with world powers.

Iran has agreed to curb some of its nuclear activities in return for about $7bn (£4.3bn) in sanctions relief. In return, some EU sanctions on the country could be lifted as early as December.

Israel called the plan a "historic mistake".
