Indian and Chinese military force fought with each other at the border in a disputed Himalayan area which occurred casualties on both sides as many injured and died.
According to the Indian source, at least 20 Indian soldiers have been killed. But China has not mentioned the numbers yet.
Tuesday's battle was reportedly fought with rocks and clubs and no shots were fired.
The incident occurred during a de-escalation process underway in the Galway Valley in the disputed Aksai Chin-Ladakh area, where a large troop build-up has reportedly been taking place for weeks now on both sides of the border.
Both sides blame each other for the fight in the snow deserts of Ladakh.
Chinese and Indian military officials held commander-level talks earlier this month at the border personnel meeting point at Moldo to discuss ways to resolve matters related to the recent border situation and safeguard peace and stability in the border area.
