Donald Trump has accused Iran of violating the ceasefire with just 24 hours until war is set to restart, as regime officials refuse to meet JD Vance in Pakistan. 

Iran's state broadcaster IRIB says no official delegation has traveled to Islamabad to meet with the Vice President as the ceasefire is set to expire at 8pm ET Wednesday.

'Iran has Violated the Cease Fire numerous times!' Trump wrote on Truth Social Tuesday. 

The President's statement comes after Tehran threatened to 'reveal new cards on the battlefield' should the war resume.  

Iran's parliament speaker Mohammed-Bagher Ghalibaf said Monday the regime is 'prepared' to renew fighting against US-Israel forces in the Middle East. 

'We do not accept negotiations under the shadow of threats, and in the past two weeks, we have prepared to reveal new cards on the battlefield,' he wrote on X.

Trump vowed to target energy infrastructure should diplomacy fail, warning that 'lots of bombs start going off.'

Peace talks appeared shaky in recent days as Tehran refused to suspend its nuclear program and Trump imposed a naval blockade in the Strait of Hormuz, with US forces boarding and seizing tankers destined for Iranian ports.

Despite confusion and diplomatic tensions, Trump told CNBC he does not want to extend the ceasefire. 

'We don't have much time [to get a deal] ... Iran can make themselves into a strong nation again if they make a deal,' Trump said. 

Trump added that he 'expects to be bombing Iran' if talks fail by tomorrow's deadline, adding 'the military is raring to go.'

Vance is expected to arrive to Pakistan before the ceasefire expires, according to multiple reports. 

It remains uncertain whether Iran will actually attend the event or leave the Vice President alone at the negotiating table in Islamabad. 

Multiple Tehran-backed news agencies say regime officials have no plans to meet with US officials for another round of peace talks. 

Pakistani mediators said Vance and Iran's parliament speaker Ghalibaf will both arrive in Islamabad tomorrow for negotiations.

Trump's war has now entered its 53rd-day despite the President previously stating in February that Operation Epic Fury was expected to last approximately four weeks. 

US law requires the President receive authorization from congress for conflicts lasting longer than 60 days.

The White House argues this law is unconstitutional and cannot limit the President's authority as commander-in-chief. 

Republicans in the House of Representatives last week narrowly defeated a bill 213-214 that would have required Trump to withdraw all armed forces from the Iran war unless he received congressional authorization.
