  1. Non-proliferation regime

    Kelsey Davenport, director for non-proliferation policy at the US-based Arms Control Association, notes that the UN arms embargo will reportedly remain in place for five years and the ban on buying missile technology for eight. This appears to be different to what Iranian state media is reporting.

  2. Iran's hero

    Iran's moderate and reformist papers are hailing Foreign Minister Mohammad Javad Zarif as a hero, reports BBC Monitoring.

    The Qanoon newspaper carries a front-page report depicting Mr Zarif as Arash, a heroic archer from Iranian folklore. According to myth, an ancient Iranian shah and a foreign king made a peace deal under which the border would be determined by an arrow shot - and Arash's heroic effort made sure Iran gained huge swathes of territory.

    From Arash to Zarif - We endured great suffering so that Iran can transform into a shining jewel.

  5. Hans Blix on the deal

    blix stock shotgett

    I think it is very welcome... It has the potential to effect a tectonic change in the Middle East. What is the alternative? The risk of a war in the Middle East. I think this gives the chance for co-operation in the Middle East, on [Islamic State], Syria.... It is like the Cuban agreement that Obama made - it's a big change in foreign policy.

    Hans Blix, Former head of the IAEA, the nuclear watchdog

  6. 'Unmistakable threshold'

    Concerns from the states

    I do think it's very important for the United States and others to establish an unmistakable threshold here: that if the Iranians move towards nuclear weapons that could trigger the use of force against them, because I think we need to re-establish the terms on the issue of Iran not having nuclear weapons

    Dennis Ross, Former advisor on Iran to US President Barack Obama

  7. Iranian flower power

  10. Doucet: deal done

    The BBC's Chief International Correspondent tweets...

  11. An Iranian-American view

    Get involved - haveyoursay@bbc.co.uk

    Alex, California:

    I am an Iranian-American living in Los Angeles, California. I'm happy a deal was reached however I think nuclear power is a right that any nation has and bullying other nations out of their rights is no different to the bully at school taking a child's lunch box.

  12. 'They never had any interest in WMDs'

    Get involved - haveyoursay@bbc.co.uk

    David, London:

    Anyone who knows anything about Iran's history knows that they never had any interest in WMDs. From the beginning they've been at the forefront of condemning chemical weapons Saddam used against their people in a horrific war aided by America. Regardless of its brutality in other matters, Iran had no desire to build a bomb - the Americans have always known this and have finally stopped listening to Israeli propaganda that's crippled Iran's economy for absolutely nothing - an Israel armed to the teeth with nukes itself.

  13. Rouhani tweet

    Iranian President Hassan Rouhani has tweeted

  14. 'Massive celebration on the streets tonight!'

    Get involved - haveyoursay@bbc.co.uk

    Alidad Varshochi, Tehran:

    This is an historic day with potentially far-reaching implications for the Iranian economy, her politics, the wider region and ultimately Iran's people. Not only will it hopefully bring Iran out of isolation, it could pave the way for much-needed political reform by strengthening the hand of reformist elements in Iran who have been pigeon-holed since the second term of Ahmadinejad. There is so an air of hope and excitement today!

    I'm expecting massive celebration on the streets tonight!

  15. 'Ready to go'

    The press officer for the EU's chief negotiator Federica Mogherini has just tweeted this picture.

  16. 'Comparing notes'

    The BBC's reporters are raring to go...

    BBC News producer Stuart Hughes, who is outside the Austria Centre in Vienna, tweets:

  17. Life under sanctions - in Lego

    Sanctions on Iran have come just short of a total trade embargo. 

    Amir Paivar from the BBC's Persian Service explains their impact  - with the help of some Lego.

  18. 'Iran will build a bomb right under our noses'

    Get involved - haveyoursay@bbc.co.uk

    Ed Kraiza:

    Pure poppycock. Iran will build a bomb right under our noses. And we can thank Obama. Hopefully the next president will have the backbone to do what's necessary when Iran breaks the deal or "spirit" of the agreement.

  19. Reporters briefed

  20. 'Nixon-to-China' moment

    British journalist Peter Oborne writes in an analysis piece for Middle East Eye  that having accomplished a nuclear deal with Iran, US President Barack Obama may finally be worthy of his Nobel Peace Prize.

    If this deal can be bedded down I believe it could be as momentous as the historic reconciliation between the US and China in the early 1970s, which ended three decades of Chinese isolation and was one of the defining events of the twentieth century.
