Eighteen firefighters and their guide have died while battling a forest fire in China's Sichuan province, state media has reported.
The Xinhua news agency said a sudden change in wind direction led to the group becoming trapped early on Tuesday morning.
The fire in Liangshan prefecture has now spread across 1,000 hectares.
More than 2,000 firefighters and rescue workers have been sent to the area and 1,200 people have been evacuated.
The fire started on Monday at a local farm. Strong winds meant that the flames quickly spread to nearby mountains.
The dead firefighters were among a group of 22 - including one farm worker acting as their guide - who went missing. Three survivors have been found and were taken to hospital.
Local media reports that heavy clouds of smoke have been drifting into the nearby city of Xichang.
The incident comes almost exactly a year after a forest fire in another part of Liangshan prefecture which killed 30 firefighters.
