At least 100 people have been confirmed dead.

Yesterday evening, two massive explosions shook the Lebanese capital of Beirut. The first explosion, theorized to have been caused by a fireworks warehouse at Beirut’s port, caused a massive plume of smoke to rise into the air. Shortly afterward, a second explosion was triggered, this one with a massive blast radius that blew windows out of some buildings while reducing others to rubble.

The exact cause of the explosions is still under investigation, but according to Lebanese Prime Minister Hassan Diab, the cause of the larger explosion was a 2,750-ton stockpile of ammonium-nitrate, a combustible chemical used in fertilizers and mining explosives. According to officials, this stockpile had been seized from a vessel in 2014, and had been sitting in a warehouse at the dock for the past six years. It is not currently known whether the explosion was an accident or deliberate, but for the duration of the investigation, Beirut port officials will be placed under house arrest and monitored by soldiers.

“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 Diab said this morning, adding that leaving hazardous chemicals in a public space unguarded for six years is unacceptable.

Meanwhile, efforts to clear the rubble and locate survivors are ongoing. As of this morning, 100 people have been confirmed dead, while approximately 4,000 have been injured. Numerous people are still missing, with family members posting pictures to social media in an effort to track them down.

“I was in the car when we felt the huge blast, the airbags opened,” an anonymous Beirut resident told CNBC. “I ran away — it’s apocalyptic. There is no other word to describe it. We’re walking on glass, the entire area of Achrafieh.”

“We lost our people and our city. My entire apartment is destroyed,” local journalist Yumna Fawaz said.

With Lebanon in the midst of an economic crisis, as well as the ongoing COVID-19 pandemic, experts are concerned that this latest disaster could put the country on the path to a full governmental collapse.

“The government’s credibility is declining, and large elements of the public no longer believes the government is able to manage,” Eurasia Group analysts said in a note. “In our view this accelerates movement towards collapse of the current government. The economic crisis will also deepen as the port is the main trade valve and base for many stored goods awaiting clearance.”
