CAIRO (AP) — The standoff over the Strait of Hormuz escalated again Saturday as Iran reversed its reopening of the crucial waterway and fired on ships attempting to pass, in retaliation after the United States pressed ahead with its blockade of Iranian ports.

Earlier in the day, Iran announced that it was reimposing restrictions on the strait in response to a US blockade on Iranian shipping and ports. Iran has prevented vessels from crossing throughout the seven-week-long war,

Trump says the blockade of the Strait of Hormuz will remain and attacks will resume if no agreement is reached with Iran.

As President Trump again voiced optimism that Iran will "make a deal" to end the war, Tehran declared itself the regulator of Strait of Hormuz shipping.

Fatih Birol of the International Energy Agency, who orchestrated a multinational release of oil reserves, detailed the risks facing the economy now and beyond.

The U.S. and Iran remain deadlocked in the Strait of Hormuz, with no clear way forward.
