Lebanon on Friday marks three years since one of history's biggest non-nuclear explosions rocked Beirut. Yet nobody has been held to account as political and legal pressures suspend the investigation. On August 4, 2020, the massive blast at Beirut's port destroyed swathes of the Lebanese capital, killing more than 220 people and injuring at least 6,500, AFP said. Authorities said the disaster was triggered by a fire in a warehouse where a vast stockpile of industrial chemical ammonium nitrate had been haphazardly stored for years.
