Iran has rejected US President Donald Trump's 15-point plan to end the war, according to state-run Press TV.

It cited an unknown "senior political-security official" laying out five of Tehran's own conditions to bring the conflict to an end, including paying reparations for damage.

They bear no resemblance to Trump's proposals, published by Israel's Channel 12 network after US officials had confirmed their existence. They include Iran committing not to build nuclear weapons and to reopen the strategically important Strait of Hormuz.

The war began on 28 February with US and Israeli air strikes, after which Iran widened hostilities by targeting American allies in the Gulf.

On Tuesday, Trump said Iran was "desperate" for talks and that Iranian negotiators had given the US a "very significant prize".
