Dozens of raging fires in North Korea have been photographed from space.
The images taken from a Nasa satellite showed vast plumes of smoke rising from across the east and southeast areas of the secretive state, near its border with South Korea.
Many of the fires appeared to be in farm lands near rivers, which the agency said may have been lit by farmers clearing debris to help fertilise the soil.
Others were in heavily forested areas, suggesting they could be wildfires, or started by drooping wires on ageing power lines.
"Collectively, the fires were producing enough smoke to send plumes of haze drifting east over the Sea of Japan," Nasa said on its website.
The images were taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) on Nasa's Aqua satellite, earlier this week.
