The India and Pakistan Border (Urdu: ہندوستان-پاکستان سرحد), known locally as the International Border (IB), is an international border running between India and Pakistan that demarcates the Indian states and the four provinces of Pakistan. The border runs from the Line of Control (LoC), which separates the Indian controlled Kashmir from Pakistan controlled Kashmir, in the north, to Wagah, which partitioned the Indian Punjab state and Punjab Province of Pakistan, in the east. The Zero Point separates the Indian states of Gujarat and Rajasthan to Sindh province of Pakistan, in the south.
Drafted and created based upon the Radcliffe line in 1947, the border, which separates Pakistan and India from each other, traverses a variety of terrains ranging from major urban areas to inhospitable deserts. From the Arabian sea, the naval border follows the course of Manora Island of Pakistan to the course of the Mumbai Harbour, in the South east. Since independence of India and Pakistan, the border has been a site of numerous conflicts and wars between each country, and is one of the most complex borders in the world. The border's total length is 1,800 mi (2,900 km), according to the figures given by the PBS; it is also one of the most dangerous borders in the world, based on an article written in the Foreign Policy in 2011. It can be seen from space at night due to the 150,000 flood lights installed by India on about 50 thousand poles.
The border between two countries is called an international border from Gujrat/Sindh to the Line of Control. The Kashmir region is divided by the 1949 UN ceasefire line into two parts and the de facto border dividing Pakistan Administered Kashmir (Gilgit-Baltistan, Azad Kashmir) from Indian administered Kashmir has been called the Line of Control since 1972. On the south side of the border of the Jammu Division is Pakistan's Punjab border, and is called the working boundary by Pakistan (which is a recent term) but the "international border" by India.
