How long could the conflict last?

US President Donald Trump had initially threatened to obliterate Iran's power plants if Iran didn't reopen the Strait of Hormuz by today.

But Mr Trump has posted on Truth Social overnight, saying he's working with Iran to bring about a "complete and total resolution" to hostilities in the region.

He described conversations with Iranian officials as "very good and productive".

But the Iranian foreign ministry has strongly rejected the claims, saying no such talks have taken place.
