China Uses Bulldozers to Redirect Himalayan River Near Site Of Recent Fight

From the Daily Mail:

China is accused of using bulldozers to redirect Himalayan river at centre of deadly border brawl with India as satellite images show China 'constructing roads and bringing in machinery'

• The images appear to show China bringing in machinery and damming a river in the disputed border region
• Indian troops recently built a new 200ft bridge over the river on their side of the Line of Actual Control   
• India says 20 soldiers were killed in as troops fought with clubs and fists at 14,000 feet in the Himalayas
  

China has sent bulldozers to divert the course of a river near the disputed border where Chinese and Indian soldiers fought in a deadly clash at 14,000 feet on Monday, satellite images suggest.  

The images appear to show China deploying new machinery and damming a river in the Himalayan mountainside where tensions boiled over into the worst violence on the border since 1967. 

The machinery was sighted on Tuesday, having not been there a week before - and Indian media suggests the Chinese troops involved in Monday's clash might have 'surged' from these positions.   

One US-based expert said China appeared to be blocking the river which crosses the Line of Actual Control, a move which would frustrate Indian troops who have just built a new 200ft bridge on their side....
