The Kashmir conflict is one of the longest running territorial conflicts, having been a central part of the feud between India and Pakistan since 1947. Currently, the region is split between both countries. The western part is under Pakistani administration as two separate provinces: Azad Kashmir and Gilgit-Baltistan. The Eastern part is administered by India as two separate territories: Jammu-and-Kashmir and Ladakh. While the current border, known as the line of control, has been stable for decades, there are regular border incidents. The northernmost parts of the border in the high valleys of the Himalayas are not demarcated and the source of an open conflict in the region of the Siachen Glacier. In the easternmost parts of the region, China and India, the world's most populous nations, are also in disagreement over their border. This makes the region one of the most dangerous places in the World, one that could start an open conflict between two or three nuclear powers. More on India and Pakistan.
