Lebanon marks four years since port blast as war fears loom

Several marches are set to converge on the port in the afternoon to remember the victims and demand justice. Nobody has been held responsible for the August 4, 2020 disaster -- one of history's biggest non-nuclear explosions -- which also injured at least 6,500 people and devastated swathes of the capital. Authorities said the explosion was triggered by a fire in a warehouse where a stockpile of ammonium nitrate fertiliser had been haphazardly stored for years. An investigation has stalled, mired in legal and political wrangling.
