An Indian soldier shot dead his commanding officer in India-occupied Kashmir (IOK), reported BBC on Tuesday.
The incident was confirmed by the Indian Army, but no further details were given.
The BBC added that some junior officers said the argument was over a mobile phone.
Media reports further added that the soldier was disciplined for using a mobile phone and it was confiscated.
Officials said the police and army are investigating the incident, which comes amid concerns regarding morale in the Indian armed forces.
Earlier this year, a video of a soldier complaining regarding quality of food went viral. The soldier was also posted in IOK.
Indian army sources have told the BBC that morale among soldiers stationed in IOK is very low.
The soldiers are becoming increasingly uncomfortable with their role in the region, saying they fear they are effectively becoming an army of occupation.
