Banks, businesses and government offices were closed on Wednesday as Lebanon marks one year since the horrific explosion at the port of Beirut with a national day of mourning.

The grim anniversary comes amid an unprecedented economic and financial meltdown, and a political stalemate that has kept the country without a functioning government for a full year.

United in grief and anger, families of the victims and other Lebanese were planning prayers and protests later in the day.

The explosion killed at least 214 people, according to official records, and injured thousands.

It was one of the largest non-nuclear explosions in history — the result of hundreds of tons of ammonium nitrate igniting after a fire broke out.

The explosion tore through the city with such force it caused a tremor across the entire country that was heard and felt as far away as the Mediterranean island of Cyprus more than 180 miles away.

It soon emerged in documents that the highly combustible nitrates had been haphazardly stored at a port warehouse alongside other flammable material since 2014, and that multiple high-level officials over the years knew of their presence and did nothing.

A year later, there has been no accountability, and the investigation has yet to answer questions such as who ordered the shipment of the chemicals and why officials ignored repeated internal warnings of their danger.

Families of the victims planned a memorial and prayers at the still-wrecked site of the blast at Beirut port later in the day. Mass protests were also expected.

A huge metal gavel with the words “Act for Justice” was placed on a wall opposite the port with its shredded grain silos, near the words “My government did this” scrawled in black.

Flags flew at half-staff over government institutions and embassies and even medical labs and Covid-19 vaccination centres were closed to mark the day.

Reflecting the raw anger at the country’s ruling class, posters assailing authorities were hung on defaced buildings across from the port.

“Here starts your end and our beginning,” read one poster that took up the space of five floors of a high-rise. “Hostages of a murderous state,” read another.

In an extensive investigative report about the blast, Human Rights Watch (HRW) on Tuesday called for an international probe into the port blast, accusing Lebanese authorities of trying to thwart the investigation.

HRW said a lack of judicial independence, constitution-imposed immunity for high-level officials and a range of procedural and systemic flaws in the domestic investigation rendered it “incapable of credibly delivering justice.”

“Since the 1960s we have not seen an official behind bars,” said Pierre Gemayel, whose brother Yakoub was killed in his apartment in the explosion last year.

Taking part in a small protest outside the justice palace on Wednesday, he said the refusal by the political class to lift immunity from senior officials accused of negligence that led to the blast is “proof of their collusion, and that their hands are tainted with blood”.

The explosion — which destroyed and damaged thousands of homes and businesses — and the lack of accountability, have added to tensions and anguish in a country reeling from multiple crises, including an economic unravelling so severe it has been described by the World Bank as one of the worst in the past 150 years.

The crisis has led to a dramatic currency crash and hyperinflation, plunging more than half the country’s population below the poverty line.

At the Vatican, Pope Francis recalled the suffering of the Lebanese people, as he held his first weekly audience with the public since surgery a month ago.

“A year after the terrible explosion in the port of Beirut, Lebanon’s capital, that caused death and destruction, my thoughts go to that dear country, above all to the victims, to their families, to the many injured and all those who lost home and work,” the pontiff said.

“And so many lost the illusion of living,” he added.
