Live updates: Iran rejects new peace talks after Trump warns of 'last chance'

Iran has rejected another round of peace talks with the U.S., just hours after President Donald Trump said the talks in Pakistan would be Iran's "last chance" to sign a deal, or "the whole country is getting blown up." 

Trump made the comments to Fox News' Trey Yingst Sunday as the Iran war enters its 50th day. 

Here's the latest: 

US seizes Iranian-flagged cargo ship 

3:45 p.m. ET: Trump said the U.S. forcibly seized an Iranian-flagged cargo ship Sunday that tried to get around its naval blockade. 

In a post on Truth Social, Trump said a U.S. Navy guided missile destroyer warned the ship in the Gulf of Oman to stop, but it did not.

"Our Navy ship stopped them right in their tracks by blowing a hole in the engine room," Trump wrote.

He said U.S. Marines had custody of the cargo ship, named Touska, and were "seeing what’s on board!"

Iran rejects new peace talks

3:10 p.m. ET: Iran has reportedly rejected a new round of peace talks with the U.S. as President Trump ramps up threats to "knock out every single Power Plant, and every single Bridge."

According to Reuters, Iran state media reported that the country would be absent from new peace talks in Pakistan, stemming "from what it called Washington's excessive demands, unrealistic expectations, constant shifts in stance, repeated contradictions, and the ongoing naval blockade, which it considers a breach ​of the ceasefire." 

On Truth Social Sunday, Trump said the U.S. is "offering a very fair and reasonable DEAL, and I hope they take it."

"NO MORE MR. NICE GUY!" Trump wrote. 

‘Last chance’ for Iran, Trump says

9 a.m. ET: In an interview with Fox News Sunday, Trump said the upcoming peace talks between Iran and Trump's special envoy, Steve Witkoff and son-in-law Jared Kushner, will be Iran's "last chance" to sign a peace deal. The deal would include reopening the Strait of Hormuz and Iran giving up its nuclear program.

Trump also said bridges and power plants will be targeted if a deal isn't reached. 

"If Iran does not sign this deal, the whole country is getting blown up," Trump said.

Strait of Hormuz still closed

8 a.m. ET: The strait, where a fifth of the world's oil was passing through daily before the war started, remained closed to traffic Sunday. On Friday, Iran declared ships could pass if they coordinated their routes with the country and paid a toll, but the country closed the strait again Saturday. 

"It is impossible for others to pass through the Strait of Hormuz while we cannot," Iranian parliamentary Speaker Mohammed Bagher Qalibaf said in an interview aired on state television late Saturday.

Trump says war will end ‘one way or another’

8 a.m. ET: 

Trump said he still believes he'll get a peace deal with Iran, "one way or another."

"It will happen," Trump told ABC News Sunday. "One way or another. The nice way or the hard way. It’s going to happen.  You can quote me."

Trump also said U.S. officials will be in Pakistan Monday to continue negotiations. 

Ships come under fire

Several ships trying to cross the strait while it had briefly reopened were hit by gunfire Saturday. 

The British military reported that two Iranian gunboats fired on a tanker after the new restrictions were imposed, and later indicated that a container vessel had also been attacked approximately 25 nautical miles off the coast of Oman. Meanwhile, India expressed "deep concern" after two Indian-flagged vessels were forced to reverse course following gunfire reports.
