The trust deficit between India and Pakistan is also visible from space in the form of a bright orange line snaking through hundreds of miles across the earth's surface.
The line is highlighted in an image of the Indo-Gangetic plain realeased by the US National Aeronautics and Space Administration (Nasa) this week. The picture was shot by Nasa's International Space Station Expedition 28 crew using a Nikon D3S digital camera, with a 16 mm lens, on 21 August.
Expedition 28, the current, long-duration expedition to the International Space Station, was launched from Baikonur Cosmodrome in Kazakhstan on 23May. It is expected to return to the earth later this month.
A number of large and small cities, on both sides of the border can also be seen in the picture.
Among the hundreds of light clusters, the largest are those of Islamabad and New Delhi, separated by 700 kilometres, and Lahore. The major highways connecting the cities are also conspicuously seen as lines between them.
The Himalayas also stand out in the picture, even at night.
