LONDON—Four people died following an explosion in a silo that holds treated biosolids at a wastewater treatment plant near the southwest England city of Bristol, police said Thursday.
Three Wessex Water employees and one contractor died in the incident, which is not being treated as terror-related, Avon and Somerset Police Chief Inspector Mark Runacres said at a media briefing. A fifth person was injured during the explosion at the plant in the industrial area of Avonmouth, but the injuries are not considered life-threatening, Runacres said.
