US and Iranian negotiators reached a tentative agreement yesterday to extend the ceasefire in the three-month-old war by 60 days and begin a new round of talks on Iran’s nuclear programme, according to an official familiar with the matter.

Iran did not immediately confirm any deal, and the official noted that President Donald Trump has yet to sign off on it.

The emerging memorandum of understanding came as the fragile ceasefire in the war between the US and Iran appeared to be wavering. The latest flare-up in fighting occurred less than a day earlier, when Kuwait intercepted missiles fired from Iran, according to US Central Command.
