At least 20 Indian soldiers were killed in a clash with Chinese forces in Ladakh in the disputed Kashmir region, Indian officials say.
The incident follows rising tensions, and is the first deadly clash in the border area in at least 45 years.
The Indian army initially said three of its soldiers had been killed, adding that both sides suffered casualties.
But later on Tuesday, officials said a number of critically injured soldiers had died of their wounds.
India’s external affairs ministry accused China of breaking an agreement struck the previous week to respect the Line of Actual Control (LAC) in the Galwan Valley.
BBC diplomatic correspondent James Robbins says violence between two armies high up in the Himalayas is very serious, and pressure will grow on the two nuclear powers not to allow a slide into full-scale conflict.
What have both sides said about the incident?
Early on Tuesday the Indian army said three of its soldiers, including an officer, had died in a clash in the area.
Later in the day, it released a statement saying the two sides had disengaged.
It added that “17 Indian troops who were critically injured in the line of duty” and died from their injuries, taking the “total that were killed in action to 20”.
China did not confirm any casualties, but accused India in turn of crossing the border onto the Chinese side.
Chinese foreign ministry spokesman Zhao Lijian said India had crossed the border twice on Monday, “provoking and attacking Chinese personnel, resulting in serious physical confrontation between border forces on the two sides”, AFP news agency reported.
Both sides insist no bullet has been fired in four decades, and the Indian army said on Tuesday that “no shots were fired” in this latest skirmish.
How a clash that did not involve an exchange of fire could prove so lethal is unclear. There are reports that it was fought with rocks and clubs
Local media outlets reported that the Indian soldiers had been “beaten to death”.
How tense is the area?
The LAC is poorly demarcated. The presence of rivers, lakes and snowcaps means the line can shift. The soldiers either side – representing two of the world’s largest armies – come face to face at many points.
But there have been tense confrontations along the border in recent weeks.
India has accused China of sending thousands of troops into Ladakh’s Galwan valley and says China occupies 38,000sq km (14,700sq miles) of its territory. Several rounds of talks in the last three decades have failed to resolve the boundary disputes.
The two countries have fought only one war so far, in 1962, when India suffered a humiliating defeat.
In May, dozens of Indian and Chinese soldiers exchanged physical blows on the border in the north-eastern state of Sikkim. And in 2017, the two countries clashed in the region after China tried to extend a border road through a disputed plateau.
There are several reasons why tensions are rising now – but competing strategic goals lie at the root, and both sides blame each other.
India has built a new road in what experts say is the most remote and vulnerable area along the LAC in Ladakh. And India’s decision to ramp up infrastructure seems to have infuriated Beijing.
The road could boost Delhi’s capability to move men and materiel rapidly in case of a conflict.
India also disputes part of Kashmir – an ethnically diverse Himalayan region covering about 140,000sq km – with Pakistan.
Over the past week, Indian media have been reporting that troops from both sides had been gradually moving back from their stand-off positions, and that efforts were under way to de-escalate the tensions. So it will come as a surprise to many to hear of a violent clash in which three Indian soldiers were killed.
The last time the two sides exchanged any gunfire along the border was 1975, when four Indian soldiers were killed in a remote pass in north-eastern state of Arunachal Pradesh.
The details of the latest skirmish, and the emergency measures being taken to defuse it, are still unclear.
Whatever the result, the latest incident is likely to trigger a fresh wave of anti-China sentiments in India.
It will also present daunting foreign policy and security challenges to Indian Prime Minister Narendra Modi and his government, which is struggling to contain a surge of Covid-19 infections and revive an economy which looks headed for recession. 16 Jun, 2020 0
