Kurt Kokko, who specializes in explosions, estimates that there was more than ammonium nitrate in the warehouse in the port of Beirut.

Kokko, who is Tukes' group leader, has watched video clips from the Beirut explosion, which have been taken from different directions. He stresses that everything is still speculation.

- We don't know what's been in stock. Some videos show that there are smaller fireworks-like pops inside the building.

The news images show how the Beirut explosion created a yellowish color.

According to Koko, the color does not quite match what can be expected from the combustion of ammonium nitrate.

- I could imagine that there has been something else in the big warehouse building.

According to preliminary data, 2,750 tonnes of ammonium nitrate exploded in Beirut.

Kokko is interested to know whether the ammonium nitrate in stock was in bulk or in sacks.

- What else could have been there with which ammonium nitrate may have reacted. Or whatever else is on fire that has caused the explosion.

Kokko points out that ammonium nitrate is an insensitive explosive. It is not a direct explosive in itself, but something must be mixed into it.

Kokko drew attention from the news photos that in the beginning there is a clear statue that looks like a fire.

- Heat can ignite ammonium nitrate, Kokko thinks.

Kokko does not want to compare the Beirut explosion with a nuclear accident, for example. He says their policies are different.

- After all, everyone can see that this is a huge explosion with a huge hard pressure wave. The pressure wave broke the windows. In many cases, broken windows cause a significant proportion of injuries.

Kokko says the same thing happened in the Breivik explosion in Norway.

In 2011, Anders Breivik detonated a bomb in central Oslo. Most of the injuries came from glass shards.

Former CIA agent: Beirut explosion is not just caused by ammonium nitrate

An experienced Middle Eastern connoisseur interviewed by CNN also believes that the explosion involved more than just ammonium nitrate.

Former CIA agent Robert Baer believes that although ammonium nitrate was stored in the port, it did not cause an explosion. According to CNN, Baer has a lot of experience in the Middle East.

Baer suspects there have been military armaments and fuel in the warehouse. He said there might have been a gun stock in the warehouse, but it is unclear to whom it would belong.

According to Baer, ​​the orange ball of fire indicates that it is a war explosive. However, he points out that the light powder formed before the explosion also suggests that ammonium nitrate was involved and burned in the explosion. Baer also noticed other munitions fired before the big explosion.

There is no evidence that the explosion was intentional. According to Baer, ​​it may also be that the explosion was damage, but the storage of war explosives in the port raises questions. According to Baer, ​​it is possible that the truth about the cause of the explosion will never be known.

According to Lebanese news media NNA sources, the papats would have caused a fire in a warehouse near the port. Later, Lebanese Prime Minister Hassan Diab said the cause of the explosion was 2,750 tonnes of ammonium nitrate, which had been stored in the port for six years without safety regulations.

The Prime Minister has launched an investigation to find out the cause.
