The Army initially said on Tuesday that an officer and two soldiers were killed. But in a late evening statement it revised the figure to 20 saying 17 others who "were critically injured in the line of duty and exposed to sub-zero temperatures at the standoff location succumbed to their injuries."

Government sources said the Chinese side too suffered "proportionate casualties" but chose not to speculate on the number.
