(2 months later) | |
A landmark nuclear deal between Iran and world powers appears close to collapse, three years after it went into effect. Here's how it got to this point. | |

Iran has always insisted its nuclear programme is peaceful. | Iran has always insisted its nuclear programme is peaceful. |
But suspicions it was being used as a cover to develop a nuclear bomb prompted the UN Security Council, US and EU to impose crippling sanctions from 2010. | |
In 2015, Iran reached a deal with six powers - the US, UK, France, China, Russia and Germany - that saw it limit its nuclear activities in return for sanctions relief. | |
The deal restricted Iran's enrichment of uranium, which is used to make reactor fuel but also nuclear weapons. It was also required to redesign a heavy-water reactor being built, whose spent fuel would contain plutonium suitable for a bomb, and allow international inspections. | The deal restricted Iran's enrichment of uranium, which is used to make reactor fuel but also nuclear weapons.

President Donald Trump abandoned the deal in May 2018 and reinstated US sanctions. He wanted a new deal that would also curb Iran's ballistic missile programme and its involvement in regional conflicts. | |

Six days later, Iran began enriching uranium to 4.5% concentration so it could make fuel for its Bushehr power plant - beyond the 3.67% cap enshrined in the deal. | |
On 4 September, President Hassan Rouhani said Iran would also lift "all limitations" imposed on its development of centrifuges used to enrich uranium. | |
