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

President Donald Trump says he has agreed to suspend a planned bombing attack on Iran for two weeks if Iran agrees to reopen the Strait of Hormuz.

In the post on his social media platform, less than two hours before a self-imposed deadline in which he had threatened "a whole civilization could die," Trump cited conversations with Pakistani officials, including Prime Minister Shehbaz Sharif, who have been negotiating an off-ramp.

In the post, Trump said, "subject to the Islamic Republic of Iran agreeing to the COMPLETE, IMMEDIATE, and SAFE OPENING of the Strait of Hormuz, I agree to suspend the bombing and attack of Iran for a period of two weeks. This will be a double sided CEASEFIRE!"

In the post, Trump said the U.S. has received a 10-point proposal from Iran and "believe it is a workable basis on which to negotiate. Almost all of the various points of past contention have been agreed to between the United States and Iran, but a two week period will allow the Agreement to be finalized and consummated."

As Trump's deadline for Iran looms, an Islamic Revolutionary Guard Corps spokesman, Ebrahim Zolfaghari, released a statement Tuesday about Iranian attacks on Israel and U.S. interests in the Middle East, saying they will continue to be "heavier and more massive."

"The wave of effective and devastating attacks by the Iranian armed forces against the military, security, and economic infrastructure of the Zionist regime in the occupied territories and centers related to the criminal America in the region will continue, heavier and more massive," Zolfaghari said.

The spokesperson said the IRGC would target "infrastructure of the US and its allies to deprive them of the region's oil and gas for years and force them to leave the region."

President Donald Trump has been made aware of Pakistan's proposed two-week deadline extension and "a response will come," White House press secretary Karoline Leavitt told ABC News.

The prime minister of Pakistan is asking President Donald Trump to extend the deadline he set for Iran, saying diplomatic efforts are "progressing."

"Diplomatic efforts for peaceful settlement of the ongoing war in the Middle East are progressing steadily, strongly and powerfully with the potential to lead to substantive results in near future. To allow diplomacy to run its course, I earnestly request President Trump to extend the deadline for two weeks," the prime minister said in a statement.

He went on, "Pakistan, in all sincerity, requests the Iranian brothers to open Strait of Hormuz for a corresponding period of two weeks as a goodwill gesture. We also urge all warring parties to observe a ceasefire everywhere for two weeks to allow diplomacy to achieve conclusive termination of war, in the interest of long-term peace and stability in the region."
