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

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."

Iranian-affiliated cyber actors are targeting U.S. critical infrastructure, according to a new warning from the federal government.

Numerous agencies, including the FBI and NSA, "are urgently warning U.S. organizations of ongoing cyber exploitation of internet-connected operational technology (OT) devices, including Rockwell Automation/Allen-Bradley-manufactured programmable logic controllers (PLCs), across multiple U.S. critical infrastructure sectors," according to an alert published on Tuesday.

Multiple critical infrastructure sectors experienced disruptions, and in some cases "this activity has resulted in operational disruption and financial loss," the alert said.

The Iranian-backed group has targeted government services industry, water and wastewater systems and the energy sector, according to the agencies.

Iranian-backed actors have carried out similar actions in the past, according to the government.

Pope Leo XIV said Tuesday that U.S. President Donald Trump's threat to destroy Iranian civilization was "truly unacceptable" and said any attacks on civilian infrastructure violate international law.

In some of his strongest comments yet against the war, Leo urged Americans and other people of good will to contact their political leaders and congressional representatives to demand they reject war and work for peace.

"Today as we all know there was this threat against all the people of Iran. This is truly unacceptable," he said.

Leo spoke to reporters as he left his country house in Castel Gandolfo, south of Rome.

He referred to Trump's threat that a "whole civilization will die tonight" if Iran fails to meet his latest deadline to strike a deal that includes reopening the Strait of Hormuz.

The U.S. carried out strikes against approximately 50 military targets on Kharg Island on Tuesday that had previously been struck last month, according to a U.S. official.

In mid-March, the U.S. struck 90 military targets on the island, which is Iran's oil transportation hub. Those 90 targets were described then as including storage bunkers for naval lines and missiles, and other military infrastructure.

The island itself is roughly the same size as Key West, Florida, or a third the size of the island of Manhattan.
