The United States (US) – led by President Donald Trump – has just pulled out of the Iran nuclear deal.
The deal is a special agreement between the country of Iran and other major world powers – the US, UK, France, China, Russia and Germany.
What is the Iran deal?
In 2015, the President of Iran agreed a deal called the Joint Comprehensive Plan of Action with six major world powers – the US, UK, France, China, Russia and Germany.
This became known as the Iran nuclear deal.
The deal meant that Iran had to stop large parts of its nuclear programme and allow international inspectors to monitor what was going on. The other countries had to take away restrictions that had been placed on Iran, such as not trading oil.
At the time the deal was announced, it was described by leaders as a “shared commitment to peace and to join hands in order to make our world safer”.
US President Donald Trump made an announcement on 8 May 2018 that the US would be withdrawing from the Iran deal
He says he will put economic sanctions back on Iran, which had been lifted after the nuclear deal was signed.
The US sanctions will cover lots of industries – including transport, oil and banking – and will gradually come back into force over next six months.
How has the world responded?
Former US President, Barack Obama, has said that what President Trump has done is “misguided”.
European leaders have said they “regret” his decision.
Iranian President Rouhani has said he will talk with other members of the deal about what happens next.
