Lighting sparked a forest fire in mountainous western China last month that killed 27 firefighters and four local helpers in one of the country’s deadliest days for first responders, investigators said.
Acting on accounts of eyewitnesses in Sichuan province’s Muli county, investigators located an 18-meter (59-foot) pine tree split by lightning that they identified as the fire’s origin point.
