Iran live updates: Trump announces he's extending ceasefire

President Donald Trump announced he is continuing the blockade and will "extend the Ceasefire until such time as their proposal is submitted, and discussions are concluded, one way or the other."

The U.S. will "hold our Attack on the Country of Iran until such time as their leaders and representatives can come up with a unified proposal," Trump said in a post on social media.

This comes hours after Trump told CNBC he did not want to extend the ceasefire and threatened continued bombing. He also said Iran had no choice but to accept a deal.

No final decision has been made on whether Iran will attend the Pakistan ceasefire talks, a spokesman for Iran's Foreign Ministry, Esmaeil Baqaei, said on Tuesday.

"It is not due to indecision," he added, but rather due to "contradictory messages, inconsistent behavior, and unacceptable actions by the American side," he said in a phone interview on Iranian state TV.

"From the very outset, we have faced violations of the ceasefire by the opposing side, including measures such as a naval blockade," Baqaei said, adding that Iran will pursue a diplomatic track "whenever it determines that such a path serves its national interests."

United States Indo-Pacific Command (INDOPACOM) said in a post to X on Tuesday that American forces interdicted and boarded an Iran-linked cargo vessel overnight.

"U.S. forces conducted a right-of-visit, maritime interdiction and boarding of the stateless sanctioned M/T Tifani without incident in the INDOPACOM area of responsibility," the command said.

"We will pursue global maritime enforcement efforts to disrupt illicit networks and interdict sanctioned vessels providing material support to Iran -- anywhere they operate," the command's statement said."International waters are not a refuge for sanctioned vessels."

INDOPACOM posted video footage of the boarding operation, which showed helicopter-borne U.S. forces rappelling onto the deck of the Tifani.

President Donald Trump alleged that Iran had "Violated the Cease Fire numerous times!" in a social media post on Tuesday morning.

The president did not elaborate on what incidents his post referred to.

The two-week ceasefire announced by Trump on April 8 is due to expire on Wednesday.
