A cycle of threat, detente and deadlock repeats itself wearisomely as the president’s war in Iran drags on

• US politics live – latest updates

As the story of the US-Iran war is written direct to social media, Donald Trump may be the genre’s premier unreliable narrator.

Since the war began, Trump has again and again threatened Iran with fearsome consequences if Tehran doesn’t come to the table and sign a peace deal that the US president said was imminent weeks ago. And he has also repeatedly claimed that an Iran deal is “close” – without any result. (A CNN tally put the number of times he’s claimed it at 38.)

Explosions reported across Iran after Donald Trump vowed to ‘hit them hard again’, with Bahrain, Kuwait and Jordan targeted by Tehran

The US launched a new round of airstrikes on Iran into Thursday morning after Donald Trump warned Tehran would “pay the price” for stalled negotiations, prompting Iran to respond with strikes targeting Bahrain, Kuwait and Jordan.

The new US assault across a range of Iranian cities came as efforts to negotiate an end to the war again appeared stuck, with Iran insisting it would maintain its chokehold on the strait of Hormuz. The American attack appeared more intense and wider than the day before, but Iran released no information about what was hit.
