Trump calls Strait of Hormuz 'something that we don't need'

Thousands of people gathered on Wednesday in Tehran’s Enqelab Square, where funerals were being held for several Iranian commanders and others killed amid the U.S.-Israeli strikes.

Video broadcast by Iranian state TV appeared to show floats carrying the photos and coffins of the deceased, including young children, to the square.

Photos taken by wire services showed huge crowds of people, including many who were holding Iranian flags, swarming the square.

Among those who will be buried are Mohammad Pakpour, who headed the Islamic Revolutionary Guards Corps; Lt. Gen. Abdolrahim Mousavi, who was chief of staff of Iran’s armed forces; Adm. Ali Shamkhani, who led the Supreme National Security Council; the former defense minister, Maj. Gen. Aziz Nasirzadeh; and Mohammad Shirazi, who headed the military bureau.

Iran’s Islamic Revolutionary Guard Corps said it launched overnight its "most intense and heaviest operation," according to Iranian state media.

The wave of attacks, which Iran said was aimed at U.S. and Israeli targets, included some three hours of missile launches, including the firing of a "Khorramshahr," a type of medium-range ballistic missile, state media reported.

"We continue to carry out our continuous attacks with purpose and power, and in the continuation of the war, we only think about the complete surrender of the enemy," the IRGC told Iranian state media. "We will end the war when the shadow of war is lifted from the country."

The Israel Defense Forces said on social media overnight that it had detected missiles launches from Iran toward Israel, saying that its defense systems were working to destroy the missiles.

The ministries of defense in both the United Arab Emirates and Bahrain warned residents early on Wednesday of potential threats. Sirens were sounding in Bahrain, the country's ministry said on social media.

"MOD asserts that the sounds heard are the result of the Air Defence Systems intercepting missiles and drones," the UAE ministry said on social media.
