Still no answers three years after Beirut mega-explosion
Three years on, the probe into the traumatic disaster caused by a huge pile of poorly-stored fertiliser remains bogged down in legal and political wrangling, to the dismay of victims' families.
The mega-blast
The massive explosion, heard as far away as Cyprus, destroys much of Beirut port and entire districts of the city in scenes that shock the country and the world.
The blast leaves a 43-metre (141 foot) deep crater and registers as the equivalent of a magnitude 3.3 earthquake.
The disaster spreads fear and chaos, with mountains of broken glass littering roads and bloodied survivors flooding overwhelmed hospitals.
The blast was caused by a fire in a warehouse where a vast stockpile of the industrial chemical ammonium nitrate had been haphazardly stored for years.
The tragedy strikes amid a deep economic crisis, almost a year after mass demonstrations erupted against a ruling class deemed inept and corrupt as living conditions worsen.
On August 10, Prime Minister Hassan Diab resigns under a barrage of pressure over the explosion.
Probe thwarted
In December 2020, the lead investigator examining the blast, Fadi Sawan, charges Diab and three ex-ministers with negligence.
Two of them file a complaint, the probe is suspended, and Sawan is removed from his post by court order.
In July 2021, the new investigating magistrate, Tarek Bitar, moves to interrogate four former ministers but parliament stalls on lifting their immunity.
He is forced to suspend the probe following a series of court challenges.
Gun battle
In October 2021, the powerful Shiite movement Hezbollah and its ally Amal call for demonstrations to demand Bitar's dismissal.
Seven people are killed in gun battles during the rally.
At the end of 2021, Bitar resumes his investigation but less than two weeks later is forced to suspend work for a fourth time following more legal challenges.
Silos collapse
On August 4, 2022, several grain silos damaged in the explosion collapse in a cloud of dust, a traumatic reminder of the disaster that struck exactly two years before.
Days earlier, other parts of the silos crumbled after a fire broke out when remaining grain stocks fermented and ignited in the summer heat.
Judicial showdown
In January 2023, 13 months after his probe is suspended, Bitar resumes work and charges Prosecutor General Ghassan Oueidat and seven others with probable intent to murder, arson and other crimes.
Oueidat in turn charges Bitar with insubordination and "usurping power" but the investigator refuses to step down.
Oueidat also orders the release "of all those detained" over the port blast, leaving the investigation stalled and nobody yet held to account.
Victims' families and rights groups urge the United Nations to create an independent fact-finding mission.
