The Siachen Conflict, sometimes referred to as The Siachen War was a military conflict between India and Pakistan over the disputed Siachen Glacier region in Kashmir. It began in 1984 with India's Operation Meghdoot.
The Siachen conflict is the highest altitude war in history.[4][5] Both countries held their positions at nearly 7 km above sea level. More than 4000 people have died in this inhospitable terrain, mostly due to weather extremities and the natural hazards of mountain warfare.citation needed
