Iran live updates: US blockade of Iran's Strait of Hormuz ports to begin Monday

The announcement of a temporary ceasefire "may create transit opportunities, but it does not yet provide full maritime certainty," in the Strait of Hormuz, Danish shipping company Maersk told ABC News in a statement on Wednesday.

Maersk, one of the largest container shipping groups in the world, said it welcomed the announcement of a ceasefire but that, "information and details available remain very limited and we are working with urgency to obtain further clarity."

"Any decision to transit the Strait of Hormuz will be based on continuous risk assessments, close monitoring of the security situation, and available guidance from relevant authorities and partners," the group said, adding that for now, no changes were being made to its services.

The Israel Defense Forces said on Wednesday that it was continuing "combat and ground operations" against Hezbollah in Lebanon, while at least one Israeli airstrike was reported in the southern city of Tyre.

Israeli Prime Minister Benjamin Netanyahu said overnight that the two-week ceasefire with Iran "does not include Lebanon," though Pakistani Prime Minister Shehbaz Sharif said the country was covered by the ceasefire announced on Tuesday.

The IDF issued multiple evacuation warnings in Lebanon on Wednesday morning, including in the city of Tyre and for all residents of Beirut's southern suburbs.

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.
