Rafts of missing Russians found in China
A major search and rescue operation is taking place along the length of the Yurungkash River, involving more than a thousand people. Police, army units and local residents are taking part. The Chinese government has provided a helicopter.
On Tuesday, Russian rescuers arrived in China to help find the missing tourists. All six are experienced rafters.
The area around the Yurungkash river has been split up into three main search zones.
The region's landscape is notoriously difficult to negotiate, and some areas can only be searched by air.
