According to Indian media reports, Chinese authorities have released ten Indian soldiers arrested after a border clash between India and China on Monday night.
Twenty Indian soldiers, including a colonel, were killed in the skirmish.
The Indian newspaper The Hindu quoted military sources as saying on Friday that those released included a lieutenant colonel and three majors.
The Indian government has not confirmed the reports, nor has it confirmed whether its troops were missing or Chinese detainees.
China has not confirmed any casualties among its troops, while 76 Indian soldiers have been injured. Both countries have accused each other of trespassing on their borders.
This is not the first clash between the two nuclear powers without conventional weapons. The two countries have a history of two-way fighting between India and China over the 2,100-mile-long unclear border or LAC.
The last exchange of fire between the two countries was in 1975 at a remote pass in the northeastern state of Arunachal Pradesh in which four Indian soldiers were killed. The incident was called an ambush by various former diplomats.
Since then, there has never been a shootout between the two sides.
This is because of the bilateral agreement of 1996, under which “neither side will fire within two kilo meters of either side of the LAC, nor will any act with explosives.”
But there have been other incidents of tension in recent weeks. In May, there were clashes between Indian and Chinese troops on Lake Pengong, Ladakh and on the borders with the northeastern Indian state of Sikkim.
India has accused China of sending thousands of troops to Ladakh’s Galwan Valley and occupying an area of 14,700 square miles.
There have been several rounds of talks between the two countries over the past three decades to resolve border disputes, but none have proved fruitful
