Both Iran and the United States have claimed to have won the more than month-long conflict in the Middle East that has roiled global financial markets and sent oil prices skyrocketing.

The claims come after the two sides agreed to a two-week ceasefire barely an hour before US president Donald Trump's deadline to obliterate Iran was set to expire.

Speaking to AFP news agency, Trump said that the United States had won a "total victory".

"Total and complete victory. 100 percent. No question about it," he said in a brief call.

With uncertainty over arrangements for the reopening of the Strait of Hormuz to oil traffic in particular, Trump insisted there was a strong framework for a longer-term deal.

The fate of Iran's store of enriched uranium is another key question, after a war that the US president said was partially aimed at ensuring Iran could never get a nuclear weapon. But Trump insisted that the nuclear material would be covered by any peace deal.

"That will be perfectly taken care of, or I wouldn't have settled," Trump said, without giving any specifics about what would happen to the uranium.

Trump also said he believed China had helped get Tehran to negotiate.

Iran, for its part, also cast the ceasefire as a win and said it had agreed to talks with Washington to begin on Friday in Pakistan on a path to end the conflict.

"The enemy has suffered an undeniable, historic and crushing defeat in its cowardly, illegal and criminal war against the Iranian nation," said a statement from the Iranian Supreme National Security Council.
