Fire erupted at a petrochemical plant in Texas, sending nine workers to a hospital and causing a huge plume of smoke visible for miles.
Emergency responders were called to help around 3pm local time (9pm BST) on Friday at the Shell facility in Deer Park, a suburb east of Houston.
Harris County Sheriff Ed Gonzalez said earlier in the day that five contracted employees were hospitalized for precautionary reasons, adding that they did not sustain burn injuries.
