Satellite images from the Galwan Valley in eastern Ladakh show how the clash between India and China erupted after days of build-up. The clash took place at a point called PP-14 or Patrolling Point 14 a few km from the Line of Actual Control (LAC), the de-facto border between India and China. New satellite images from Reuters taken on Tuesday shows a massive build-up on the Chinese side of the LAC.
