Our live coverage has concluded, but you can read more about today's events here: Trump says deal to end Iran war is close after calling off strikes
Donald Trump says he has "cancelled" strikes against Iran saying negotiations with Tehran were "brought to the highest level of Iranian leadership and approved"
"Discussions and final points have been, in both concept and great detail, approved by all parties involved," Trump says - elaborating further in remarks in the Oval Office
However, Iran says a deal is yet to be finalised and earlier warned the US of an "endless quagmire that you will be stuck in for years" about more strikes
Trump's mixed messaging on Iran has left key details unanswered and raised fresh questions about the state of negotiations, writes our Washington correspondent
The US has confirmed it carried out a strike on Guinea-Bissau-flagged vessel Jalveer.
Central Command (Centcom) says the ship "violated the blockade" by attempting to transport Iranian oil through the Gulf of Oman.
It is the third vessel struck by US forces in the Gulf this week after attacks on the Marivex and Settebello vessels, according to Centcom.
Image source, US CentcomIndia's ministry of external affairs has accused the US of striking a third ship carrying Indian sailors near the Shinas port of Oman this morning.
Jalveer, a Guinea-Bissau-flagged vessel, had 20 Indian sailors on board, all of whom are reportedly safe, according to India's shipping ministry, which says evacuation is still in progress.
In a press conference in New Dehli this morning, the ministry of external affairs said three separate strikes on the Settebello, Marivex and Jalveer vessels "came from the US Navy".
US Central Command (Centcom) has confirmed strikes on Settebello and Marivex but is yet to comment on reported strikes on Jalveer.
Ministers added that 13 Indian-flagged vessels and more than 18,000 Indian sailors remained stranded in the Gulf region, including 562 on Indian-flagged ships.
The US struck an Iranian cargo vessel carrying "essential goods" in the Gulf of Oman this morning, according to the governor of Sirik, who was quoted by Iran's semi-official state news agency Mehr news.
Five crew members were rescued after a projectile hit the vessel, which was reportedly struck as it departed from the city of Khasab, Oman, towards the Iranian city of Sirik.
The US has not commented on the reported strike.
The M/T Settebello was the eighth ship to be disabled by US forces since the start of its blockade of Iran's Gulf Coast, according to US Central Command (Centcom).
The US initiated its blockade of Iranian ports in the Strait of Hormuz on 13 April, and has been intercepting or turning back vessels travelling to or from Iran's coast.
Centcom says 134 ships have been redirected after complying with US forces, while eight non-compliant vessels - including the Palau-flagged Settebello - have been "disabled". The tanker was struck by US forces on Wednesday, resulting in the deaths of three Indian sailors.
It adds that US forces have allowed 42 humanitarian ships to pass through the waterway since the blockade began.
Meanwhile, Donald Trump also claimed on Wednesday that the US military had helped 200 commercial ships pass through the strait as part of a "secret mission".
Iran, however, insists the shipping channel is "completely closed".

India has summoned a senior American diplomat after three Indian sailors were killed in a US strike on an oil tanker near Oman.
India’s Ministry of Foreign Affairs summoned Jason Meeks, the US Embassy’s deputy chief of mission in New Delhi, to lodge a "strong protest".
The three Indian sailors who were killed in the strike on the Palau-flagged Settebello on Wednesday have been identified as deck cadet Aditya Sharma, engine fitter Shivanand Chaurasia and chief engineer Patnala Suresh.
Earlier today, India's shipping minister described their deaths an "irreparable loss" and said he was "deeply saddened" to learn about the "tragic incident".
He added that their bodies would be returned to India at the earliest opportunity.
Yesterday, US Central Command said it had disabled an oil tanker as it transited the Gulf of Oman, accusing it of violating its blockade of Iranian ports in the Strait of Hormuz.

Sandwiched between Iran, Oman and the United Arab Emirates, the Strait of Hormuz is one of the most vital shipping lanes in the world.
Around 20% of the world's oil and liquefied natural gas usually passes through the tight waterway but it was effectively cut off by Iran after the US and Israel launched wide-ranging strikes on 28 February.
The closing of the strait has sent oil prices soaring globally.
The US established a blockade of Iranian ports in early April after a ceasefire was agreed.
US President Donald Trump has said the blockade will remain "in full force and effect until an agreement is reached, certified, and signed".
Image source, ReutersThe father of a sailor killed in the US attack on oil tanker Settebello says he last spoke to his son on Tuesday, and "everything was alright".
Ramji Chaurasiya tells Reuters that his son had left home eight or nine months ago.
Chaurasiya says he was informed that a bomb had been dropped on the ship and that several crew members were missing.
When asked what information he had received, the father breaks down in tears.
Debate is continuing between Iran and the US over the closure of the Strait of Hormuz.
On Wednesday, Iranian state media reported the busy shipping channel was "completely closed to all type of vessel".
On Thursday morning, Iran's waterway authority says again the strait is closed, state media reports, following a new wave of US strikes yesterday.
However, overnight US Central Command denied its closure, writing: "Commercial ships are continuing to transit in and out of the Strait of Hormuz tonight."
The Strait of Hormuz remains at centre of negotiations, with both the US and Iran attempting to exert control over its future.
Iran has been blocking the waterway since the beginning of the war leaving thousands of sailors stranded, with the US imposing a blockade on Iranian ports in retaliation.
Iran has created the Persian Gulf Strait Authority, which it says will allow the Iranian army to oversee vessels moving through after the war.
But the US insists Iran will not be allowed to control the strait after the war - Donald Trump claimed on Wednesday that the US military had helped 200 commercial ships pass through the waterway as part of a "secret mission".
Iran’s foreign ministry has said the latest US strikes leave the ceasefire between the countries “practically meaningless”.
In a statement, the ministry strongly condemns the “illegal and criminal attacks” carried out by the US, claiming they violate the UN Charter and fundamental rules of international law.
It adds that US leaders will be responsible for the consequences of the escalation.
It comes after US Central Command said it completed a wave of “self-defense strikes” targeting military, surveillance and radar sites in southern Iran on Wednesday.
Iran also carried out strikes, targeting US military assets across the region in Bahrain, Kuwait and Jordan.
Announcing the death of three Indian sailors after the US struck an oil tanker, India’s Shipping Minister Sarbananda Sonowal says it was “deeply unfortunate to learn of the tragic incident”.
In a post on X, he adds that it's a "profound loss".
The Palau-flagged Settebello came under attack on Wednesday after the US military accused it of violating an American blockade by "attempting to transport oil from Iran". There were 24 Indian crewmen on board - 21 were rescued.
The US Central Command said it fired munitions into the ship’s engine room after crew “repeatedly failed to comply” with American forces.
Manoj Yadav, general secretary of the Forward Seamen's Union of India, told The Economic Times newspaper that he "refused to believe" that the US lacked information regarding the nationalities of the people on board those ships. He said detaining the ships instead was a “viable alternative”.
This is the second vessel with Indian crew that has come under attack this week. On Monday, US forces hit Marivex, also a Palau-flagged oil tanker with an Indian crew, in the Gulf of Oman after it failed to comply with US instructions, Centcom said.
All 24 crew were rescued by the Omani military, Indian authorities said.

Three Indian sailors were killed after a US strike on the Palau-flagged Settebello, New Delhi’s Shipping Minister Sarbananda Sonowal has announced, describing it as "deeply unfortunate".
On Wednesday, US Central Command said it had disabled the oil tanker, accusing it of violating the ongoing blockade of the shipping channel the Strait of Hormuz.
India's government had initially said three Indian sailors were missing and 21 Indian crew members had been rescued.
Meanwhile, the Indian embassy in Oman said it was investigating a separate incident involving a vessel off the Shinas port in Oman, which took place in the early hours of Thursday morning.
It's the latest in a series of strikes on vessels operating around the coast of Oman this week – on Monday the US said it disabled a different oil tanker, another Palau-flagged vessel, the Marivex.
The ceasefire between the US and Iran is under increasing strain after the two sides exchanged fire for a second consecutive day on Wednesday, with both sides targeting military sites.
Despite the escalation of strikes, three Iranian sources told Reuters this morning that diplomatic efforts had intensified, with negotiations centring around the release of frozen Iranian funds.
