President Trump says US Navy will begin blockade of Strait of Hormuz

In a late- night social media post following the announcement of a two-week ceasefire deal, President Donald Trump called it "a big day for World Peace!" and claimed that the U.S. "will be helping with the traffic buildup in the Strait of Hormuz."

"There will be lots of positive action! Big money will be made. Iran can start the reconstruction process. We’ll be loading up with supplies of all kinds, and just 'hangin' around' in order to make sure that everything goes well. I feel confident that it will," Trump said in the post.

Earlier Tuesday, Trump said that a two-week ceasefire with Iran was contingent on agreeing to "the COMPLETE, IMMEDIATE, and SAFE OPENING of the Strait of Hormuz."

It’s unclear when that will happen, and what role the U.S. might play in reopening the critical waterway.

A statement from the office of Israeli Prime Minister Benjamin Netanyahu says Israel supports President Donald Trump's decision to suspend strikes against Iran for two weeks subject to Iran immediately opening the Strait of Hormuz.

The two-week ceasefire does not include Lebanon, the prime minister's office said.

Following the announcement of a temporary ceasefire between the U.S. and Iran, White House press secretary Karoline Leavitt celebrated the development.

"This is a victory for the United States that President Trump and our incredible military made happen,” Leavitt said in a social media post. "From the very beginning of Operation Epic Fury, President Trump estimated this would be a 4-6 week operation."

The post went on: "The success of our military created maximum leverage, allowing President Trump and the team to engage in tough negotiations that have now created an opening for a diplomatic solution and long-term peace."

Leavitt also credited Trump, saying he "got the Strait of Hormuz reopened."

Earlier, Iran's foreign minister said in a statement the two-week deal includes "safe passage" through the strait "via coordination with Iran's Armed Forces."

Responding to President Donald Trump's ceasefire proposal, Iran declared victory Tuesday with Iran's foreign minister saying the Iranian military will "cease their defensive operations" if the U.S. halts its attacks.

Regarding the reopening of the Strait of Hormuz, Iran Foreign Minister Seyed Abbas Araghchi said: "For a period of two weeks, safe passage through the Strait of Hormuz will be possible via coordination with Iran's Armed Forces and with due consideration of technical limitations."

It was not immediately clear if such a proposal would satisfy Trump's demand for the "COMPLETE, IMMEDIATE, and SAFE" reopening of the strait.

Following Trump's announcement, a lengthy statement from Iran's Supreme National Security Council posted on Iranian state media, claimed the U.S. agreed to their plan which includes numerous concessions.

The White House has not responded directly to the claims in the statement.

White House Press Secretary Karoline Leavitt released a statement that read:

"President Trump's words speak for themselves: this is a workable basis to negotiate, and those negotiations will continue. The truth is that President Trump and our powerful military got Iran to agree to reopening the Strait of Hormuz, and negotiations will continue."

In announcing the ceasefire proposal, Trump called Iran'. 10-point plan "a workable basis on which to negotiate" but did not provide specifics.

The Supreme National Security Council said two weeks of negotiations are set to begin later this week.

White House press secretary Karoline Leavitt said there are discussions about in-person talks, "but nothing is final until announced by the President or the White House."
