Iran says it is ‘far’ from peace deal with US, as Strait of Hormuz closed again

Iran's parliamentary speaker says progress has been made in talks with the US, but that the two countries remain "far" from a peace deal.

President Donald Trump says "very good conversations" are happening with Iran, but he won't let Tehran "blackmail" the US over the Strait of Hormuz.

Iran says the Strait of Hormuz will remain closed until the US lifts its blockade on Iranian ports, which it calls a "breach of the ceasefire" - it adds it is "currently reviewing" new proposals put forward by Washington.

Trump says the blockade will continue until "our transaction with Iran is 100% complete".

Two Iranian gunboats open fire on a tanker in the Strait of Hormuz, while other ships report being hit by "unknown projectiles".

The US military says it has forced 23 ships to turn around near the Strait of Hormuz since its blockade of Iranian ports began.

Here’s an overview of negotiations between the US and Iran so far:

28 February: Conflict breaks out after the US and Israel launch strikes on Iran, as diplomatic talks collapse

6 March: Donald Trump says there will be no deal "except unconditional surrender" of Iran.

21 March: Trump sets a deadline, threatening to target Iran’s energy infrastructure unless it agrees to open the Strait of Hormuz.

23 March: Trump postpones his deadline, citing "productive conversations" - this is followed by a series of further postponements.

7 April: Trump warns “a whole civilisation will die” if the strait is not opened before another deadline.

8 April: Pakistan, acting as mediator, announces a two-week ceasefire between the US and Iran for further talks.

12 April: Trump announces a blockade of Iranian ports.

17 April: Iran’s Araghchi says the strait will remain open for the rest of the ceasefire. Trump says the US blockade will continue.

18 April: Iran’s Islamic Revolutionary Guard Corps says it will block the strait again. Trump says “very good conversations” are happening but the US will not be “blackmailed” over the waterway.
