Trump says US-Iran ceasefire still in place after exchange of fire in Strait of Hormuz

US President Donald Trump says a ceasefire is still in place with Iran, despite a clash between Iran and US naval destroyers in the Strait of Hormuz for which both sides blamed the other.

The US said Iran launched missiles, drones and small boats against three of its warships, in what it called an "unprovoked attack". Trump said Iran "trifled with us today".

Iran's top military command, meanwhile, alleged the US had targeted an Iranian oil tanker and another vessel approaching the Strait of Hormuz and carried out "aerial attacks" on several coastal areas.

The flare-up comes a day after Iran's foreign ministry had said it was considering a US proposal to end the war.
