Six workers died inside a 400-meter long water pipe under construction on Wednesday at Al-Aziziyah District south Riyadh, said Saudi Arabia’s Civil Defense.
Riyadh Civil Defense spokesman Lt. Col. Mohammad Al-Hammadi said: “The concerned authorities started investigating the causes of the accident with the company and the contractor implementing the project at the site.”
He said that the workers installing water pipes could not get out of the pipe and lost contact with their colleagues outside.
He said that the civil defense team found the workers unconscious and pulled them out from the pipe after making holes in the pipe.
The paramedics pronounced all six workers dead at the site. An investigation is still underway to determine the cause of the accident.
