Firefighters were rushed to Magħtab on Sunday afternoon to put out a fire that was inching dangerously close to the area's giant landfill.
A Civil Protection Spokesman said that all units stationed in Xemxija were sent to the site at around 4.55pm, following reports of flames spreading from a field.
They quickly put the fire - which was lit by an unknown person seemingly keen to burn a mound of rubbish - before it could spread and cause any further damage.
