The U.S. and Iran failed to reach a peace deal after 21 hours of negotiations.
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.

At least 3,546 people -- including 244 children-- have been killed in Iran since the war began, according to the U.S.-based Human Rights Activists News Agency.
At least 1,219 military personnel are included in the death toll, HRANA said.
Iranian foreign ministry spokesman Esmaeil Baqaei said that Iran has been engaging in talks with Oman on examining "a procedure for the safe passage of vessels through the Strait of Hormuz."
Baqaei said the talks with Oman have been held at the level of deputy foreign ministers.
"We think these talks will continue until coming to a conclusion," he added.

Referring to President Donald Trump's deadline threat, Baqaei said Iranians will not be "subjugated" by deadlines in defending their country.
Trump threatened to target Iran’s power plants and bridges unless the regime opens the Strait of Hormuz by Tuesday night.
Israeli Defense Minister Israel Katz said Monday that Israel launched attacks on Iran's southern petrochemical infrastructure in the Persian Gulf port city of Asaluyeh.
"Two facilities, which together are responsible for about 85% of Iran's petrochemical exports, have been taken out of service and are not functioning," Katz said.
Iran's semi-official Tasnim News Agency reported that the Mobin and Damavand companies -- which supply electricity, water and oxygen to Asaluyeh's petrochemical facilities -- were hit.
The deputy governor of the southwestern Bushehr province told the state-run IRNA agency that no casualties had been reported from the attack.
Asaluyeh's facilities were previously targeted in U.S.-Israeli attacks last month.
