Watch the various videos. The shock wave was amazing.

Mass Damage In Beirut As Explosions Rip Through Downtown

Videos on social media showed massive explosions and widespread damage near the port in Lebanon’s capital city. Multiple outlets are reporting several casualties.

One rumored cause was a possible nitrate storage facility explosion.
 
There's another report saying that the government had been storing illegal munitions, which they've been confiscating from smugglers, in warehouses near the port facilities.

Good thing the TSA just confiscates shampoo and not bombs, isn't it?
 
The report I heard sounded like these were smugglers picked-up out in the Mediterranean running guns and ammo to various factions in the Middle-East.

Well, they ain’t so smug anymore then...

"I will not rest until we find the person responsible for what happened, to hold him accountable and impose the most severe penalties," Prime Minister Hassan Diab said.

Diab said it was "unacceptable" that a shipment of ammonium nitrate estimated at 2,750 tons had been in warehouse for six years without "preventive measures" in place to protect it. The chemical compound, which is commercially available, is used widely in fertilizers and explosives.


Video of the explosion - This explosion

ammonium nitrate has a long history of unplanned explosions

Someone already added it to the list of ammonium nitrate disasters

Raw, unadultaated Ammonium Nitrate is not an explosive. Add approx 7% by weight diesel fuel to it and it becomes a different matter. There is a lot we are not being told here.
 
Trump is now suggesting that it may have been an "attack"...

Trump says massive explosion in Beirut appears to be an attack but local officials are still investigating

Watch the video in the item below. There appears to be a large number of smaller secondary explosions, possible ammunition being cooked-off, between the first explosion and the second, much larger explosion. As I posted earlier, there are reports that the warehouse that exploded, had been used to store 'munitions' taken from smugglers.

Raw, unadultaated Ammonium Nitrate is not an explosive.
Smaller quantities are not explosive.
When there is a fire in large quantities such as shiploads and large warehouses, the internal temperature rises to the point that it will explode. (Without diesel fuel)

A tragic disaster. Though macabrely fascinating from an engineering view...

The video above is incredible. Most of us have probably seen video footage of large scale explosions before however looks like it is straight out of Hollywood's special effects studios. The way buildings are ripped apart and upwards as the blast wave passes is stunning and horrifying.
 
For a first time in a 'bang' video I didn't have to scream at the vidiographer to duck-an-cover.

To paraphrase a entertaining chemistry blogger I read: "you don't go packing that many nitrogen atoms together without expecting it to eventually decided to unpack itself and everything around it".

Or to quote:
Lest you think, though, that explosions of ammonium nitrate facilities are a sepia-toned relic, that last link above will show you that every decade since has featured one or more detonations, all the way up to the huge Tianjin explosions in late 2015. Basically, any fire near a storage area for ammonium nitrate should be considered a potential disaster, and the two main options, which have to be weighed against each other depending on ones own situation, would appear to be extinguishing such a blaze as quickly as possible or getting the hell out of the entire vicinity, keeping in mind that said vicinity might have a radius of several miles.


If you are bored then there is plenty to read here about some insanely explosive compounds:
 
In the first video in the huffpost link, we see at first a fire (or something else with lots of smoke), then a large explosion with a red cloud and then the HUGE explsion with the ball shaped shockwave (?)

Does the red cloud from the first explsion indicate that something else was exploding at first, and maybe the silos (seem to be silos at the epicenter) with the nitrate second, or is this too speculative?
 
This article says that a Russian-owned, Moldovan-flagged cargo ship was transporting the amonimum-nitrate from Georgia to Mozambique when it was forced to make an unscheduled port call in Beruit.

While there the ship failed inspection, the owner abanonded the ship and crew and the crew left. The Lebanese officials siezed the cargo of amonimum-nitrate and piled it up in a building in the port. And there it sat for 6 years.
 
The red cloud is nitrogen tetroxide, released from decomposition of the nitrate due to high temperature. As waross said, get the nitrate hot enough it starts to decompose, and if the pile is big enough the decomposition can transition from a slow deflagration to a detonation.
 
Another earlier Texas disaster.
