Britain, France and Germany have pledged to remain in the Iranian nuclear deal despite Donald Trump pulling America out of the agreement.

In a joint statement the countries expressed “regret and concern” over the decision and urged Iran to “show restraint” in its response.

Hassan Rouhani, the president of Iran, said that the country would remain in the deal as discussions with allies take place over the next “few weeks”.

However he said if talks fail with other partners to the deal then Iran was prepared to restart its uranium enrichment programme.

Middle Eastern allies of America welcomed Mr Trump’s decision, with leaders in Israel and Saudi Arabia issuing messages of support.

But Federica Mogherini, the EU foreign affairs chief, said that no one would be allowed to “dismantle” the agreement and urged the Iranian people to stay committed.

Here is how the world reacted to Mr Trump’s decision to withdraw America from the deal and reimpose economic sanctions on Iran.
