The violent clash between Indian and Chinese troops in Galwan Valley of Ladakh took place without any gunshot exchange.
Soldiers from both sides engaged in hand-to-hand clashes with each other without gunfire, according to sources.
Stones, batons and metal clubs were also used in the attack as Indian troops clashed with their Chinese counterparts to push them back to the Line of Actual Control (LAC), the sources added.
The face-off led to three casualties on the Indian side, with the killing of an Indian Army officer and two soldiers, while at least 11 other soldiers were injured in violent physical skirmishes.
Tensions have been brewing between the two sides over the past few weeks. The trigger for the face-off was China's stiff opposition to India laying a key road in the Finger area around the Pangong Tso Lake besides construction of another route connecting the Darbuk-Shayok-Daulat Beg Oldie road in Galwan Valley
This is the first incident in over four decades leading to fatalities on the India-China border. In 1975, four Indian troops of Assam Rifles Jawans were killed in a Chinese ambush in Arunachal Pradesh.
Senior military officials from both sides are holding meetings in Galwan Valley of Eastern Ladakh to defuse tensions between the two countries.
