A senior Iranian official said on Wednesday that Tehran would hold a public ceremony for citizens to pay their respects following the death of the country's Supreme Leader Ayatollah Ali Khamenei, France 24 reported, citing state media, said ANI. Hojjatoleslam Mahmoudi, head of Iran's Islamic Propagation Council, said the farewell ceremony would continue for three days, and the funeral procession would be announced later. The ceremony was originally scheduled to take place at Tehran's Imam Khomeini Prayer Hall starting at 10 pm (1830 GMT) on Wednesday, but was "postponed", state media said, without elaborating further, as per France 24. Meanwhile,Iran said on Wednesday that 1,045 people have been killed in the country since Saturday as a result of U.S.-Israeli strikes, reported Xinhua. In a statement published on its official website, Iran's Foundation of Martyrs and Veteran Affairs described the strikes as "aggressive and brutal." The toll follows joint U.S.-Israeli attacks on Tehran and several other Iranian cities starting Saturday morning, which resulted in the deaths of Iran's Supreme Leader Ali Khamenei, his family members, top military commanders, and civilians. Iran has since responded with multiple waves of missile and drone attacks targeting Israel and U.S. assets across the region. Meanwhile, White House Press Secretary Karoline Leavitt said Wednesday that U.S. forces will have "complete and total dominance" over Iranian airspace in the next few hours. "We expect to have complete and total dominance over Iranian airspace in the coming hours," Leavitt said at the White House daily press briefing. She added that deploying U.S. ground troops to Iran is not currently planned, though U.S. President Donald Trump said earlier he is open to the option in the future. Earlier in the day, U.S. Defense Secretary Pete Hegseth said at a Pentagon briefing that the U.S.-Israeli military operation against Iran is still in its early stages. Dan Caine, chairman of the Joint Chiefs of Staff, said U.S. forces will begin striking progressively deeper into the Iranian territory as operations expand. Iran and the Lebanese militant group Hezbollah have conducted their first coordinated attacks on Israel amid the ongoing escalation, the Israel Defense Forces told CNN on Wednesday. Meanwhile, three people were killed and six others wounded in Israeli airstrikes targeting two vehicles on Beirut's airport road on Wednesday night, Lebanon's Ministry of Public Health said. "The Israeli enemy's two airstrikes on the airport road led to the martyrdom of three people and the injury of six others," the ministry's Public Health Emergency Operations Center said in a statement. The two vehicles were struck in Israeli raids on the airport road in Beirut earlier in the evening, the National News Agency (NNA) reported. The Israel Defense Forces (IDF) said it struck several Hezbollah targets across Lebanon on Wednesday, including rocket and missile launch sites as well as a drone manufacturing plant. The development comes as Israel has intensified airstrikes on Beirut's southern suburbs in recent days. Hezbollah on Monday fired missiles and drones toward Israel, saying the attacks were in retaliation for the killing of Iran's Supreme Leader Ali Khamenei in a U.S.-Israeli strike and for repeated Israeli attacks on Lebanon. Israel responded with massive airstrikes on Hezbollah targets and deployed ground forces into southern Lebanon. Meanwhile, Secretary of Iran's Supreme National Security Council Ali Larijani said Wednesday the United States will have to pay a "heavy price" for killing the country's Supreme Leader Ali Khamenei, reported Xinhua. Writing on social media platform X, Larijani said U.S. President Donald Trump dragged the American people into an "unjust" war with Iran. He added, "Now he must calculate: with over 500 American soldiers killed in just the past few days, does America still come first -- or Israel?" Meanwhile, the Israeli military said it carried out large-scale airstrikes in eastern Tehran on Wednesday, targeting a sprawling military compound that houses multiple command centers for Iran's security and intelligence organizations. In a statement, the military said the operation was directed at facilities used as headquarters for the Islamic Revolutionary Guard Corps (IRGC), the elite Quds Force, the Intelligence Directorate, the Basij volunteer force affiliated with the IRGC, internal security units, and the cyber warfare. Iranian personnel responsible for operating the facility were also targeted, it said. Earlier in the day, the Israeli military said it is "continuing to deepen" its attacks across Iran, revealing that it had dropped more than 5,000 munitions on the country since the joint U.S.-Israeli operation began on Saturday. Meanwhile, Iran said 1,045 people have been killed in the country since Saturday as a result of the U.S.-Israeli operation. The joint U.S.-Israeli military operation against Iran, entering its fifth day, has triggered a sharp escalation across the Middle East, setting off waves of missile exchanges, mounting casualties, and far-reaching political, security, and economic repercussions.
