Overview
- Authorities confirm four adult fatalities, mostly motorists caught in traffic at the site.
- At least 17 people were injured, including ten in serious condition, with several others arriving at hospitals on their own.
- The blast followed a rollover at Route 5 and General Velásquez in Renca, where flames engulfed at least seven vehicles and damaged nearby facilities within an estimated 150–200 meters.
- Regional officials say the leading hypothesis is a failure in a truck valve that released gas, which detonated after a spark.
- Emergency crews and forensic teams remain on scene, casualty and damage counts are provisional, and the event has renewed scrutiny of hazardous-fuel transport on urban highways.
