Dubai, United Arab Emirates - The Iranian president visited those injured on Sunday, and an outbreak of one of the major ports in the Islamic Republic, the facility is allegedly linked to earlier delivery of chemical components to make missile propellants.

The visit of President Masoud Pezeshkian came in amid a bombing on Saturday, with visits at the Shahid Rajaei port outside Bandar Abbas in the southern Iranian province of Hormozgan fell to 40 deaths and about 1,000 injured.

Although Iranian troops try to deny the delivery of ammonium perchlorate from the Chinese colony, new videos emerge, showing the doomsday scene in the still-wandering port. The craters deep in the meter (code) appeared surrounded by burning smoke so dangerously that authorities closed schools and businesses in the area.

The container seemed to be smashed or thrown, like discarded toys, while the bodies of burning trucks and cars sat on the scene.

"We have to find out why it happened," Pezshkian said in a meeting with officials broadcasting with Iran State TV.

Iran's top leader, Ayatollah Ali Khamenei, 86, expressed his condolences in the explosion and opened up the possibility of destructive explosions.

"It is the responsibility of security officials and judicial authorities to conduct a thorough investigation to detect whether any negligence or intentional conduct has caused this problem and follow up on it in accordance with regulations," his name said. "All officials must know that preventing pain and destructive incidents are their responsibility."

Authorities described the fire as being under control, saying first responders hope to put out completely later Sunday. Overnight, helicopters and heavy cargo planes flew over the burning port and dumped sea water on the scene. Satellite pictures taken by Planet Labs PBC on Sunday and analyzed by the Associated Press showed that there was still a large amount of black smoke at the scene.

Governor Mohammad Ashouri gave the latest death toll, according to Iran State Television. Pir Hossein Kolivand, head of the Iranian Red Crescent Society, said only about 1,000 injured people were still hospitalized, according to a statement from the Iranian government website. The governor announced three days of mourning.

Private security company Ambrey said the port received missile fuel chemistry in March. This is the first report by the Financial Times in January that it is part of ammonium perchlorate shipped from China to China. Chemicals used to make rocket solid propellants will be used to supplement Iran's missile stockpile due to its direct attack on Israel during the Hamas war in the Gaza Strip.

As Ambrey said, the ship tracking data analyzed by the AP will be a ship believed to be carrying a nearby ship in March.

“The fire was reportedly due to the result of improper handling of solid fuels designed to be used for Iranian ballistic missiles.”

In its first reaction on Sunday, General Reza Talaeinik, spokesman for the Iranian Ministry of Defense, denied importing missile fuel through ports.

"There is no (OR) at the port, no imported and imported or exported fuel or military cargo," he told state television via phone. He called for unfounded foreign reports about missile fuel, but did not provide any explanation for detonation of materials detonated with such incredible power at the scene. Talaeinik promised authorities will provide more information later.

It is unclear why Iran will not move chemicals from ports, especially after the 2020 Beirut port explosion. The explosion was caused by hundreds of tons of highly explosive nitrate ignition, killing more than 200 people and injuring more than 6,000 people. However, Israel did target Tehran using industrial mixers to create solid fuel Iranian missile sites, meaning it may not have a place to deal with the chemical.

Red smoke rose from the fire before the explosion Saturday in social media footage of Shahid Rajaei's explosion. This suggests that compounds were involved in the explosion, just like in the Beirut explosion.

Meanwhile, Russian President Vladimir Putin deployed several emergency planes to Bandar Abbas on Sunday to provide assistance.
