CENTCOM said it will block all traffic 'entering and exiting Iranian ports.'
President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military and government sites.
Trump set a deadline for Iran to fully reopen the Strait of Hormuz or face broad strikes on its critical infrastructure. Hours before the deadline expired, Trump said he had agreed to suspend planned bombing for two weeks if Iran agreed to reopen the Strait of Hormuz.
Iranian Foreign Minister Abbas Araghchi then said that "safe passage through the Strait of Hormuz will be possible via coordination with Iran's Armed Forces and with due consideration of technical limitations."
Israeli Prime Minister Benjamin Netanyahu said he supported the ceasefire with Iran, but that Lebanon -- where intense Israeli strikes continued -- was not covered by the agreement, despite Iranian protests.
The United States struck military targets on Kharg Island overnight, according to a U.S. official.
These strikes targeted some of the same military targets struck in the earlier strike in March, though the official stressed that these strikes did not target the island's oil infrastructure.
A synagogue in Tehran was "completely destroyed" in U.S.-Israeli strikes overnight, the official Islamic Republic News Agency reported on Tuesday.
Located in central Tehran, Rafi-Nia Synagogue served as a religious center for the city's Jewish community, the semi-official ISNA News Agency reported.
The attacks were condemned by Homayoun Sameh Najafabadi, the representative of the Jewish community in Iran's parliament, according to IRNA. He said that carrying out the strikes during the Passover holiday showed that Israel had an "anti-religious attitude."
"At the beginning of the attack on our country, Trump claimed that he was carrying out these strikes in support of the people. But later, most of those who were martyred, injured, or disabled by the United States and Israel were these same people," Najafabadi said.
Iran's Deputy Minister of Sports and Youth Alireza Rahimi invited people to form human chains around the country's power plants in a video message published on Monday, according to the government's Telegram channel.
Rahimi called on young people, artists, athletes, students and professors to join the initiative -- which he described as a "symbolic move" -- on Tuesday at 2 p.m. local time (6:30 a.m. ET), regardless of their political views, to protect infrastructure he referred to as "national assets that belong to the future of Iran and its young people."
The invitation came as President Donald Trump's Tuesday evening deadline for Iran to fully re-open the Strait of Hormuz approached. Trump has threatened to destroy Iranian civilian infrastructure -- including power plants and bridges -- if Tehran does not comply.
Israeli attacks on Iranian infrastructure, meanwhile, have intensified across the country.
The Israel Defense Forces' Farsi language X account on Tuesday morning issued a warning to all Iranians to "refrain from using and traveling by train throughout Iran" until 9 p.m. local time.
"Your presence on trains and near railway lines endangers your life," the post said.
