During the 1980's civil war, which Middle Eastern city was divided by a 'Green Line'?

The Green Line was a line of demarcation in Beirut, Lebanon during the Lebanese Civil War from 1975 to 1990. It separated the mainly Muslim factions in predominantly Muslim West Beirut from the predominantly Christian East Beirut controlled by the Lebanese Front. However, as the Civil War continued, it also came to separate Druze from Alewite, and Sunni from Shia.

At the beginning of the Civil War, the division was not absolute as some Muslims lived East of the Green Line and some Christians lived in West Beirut but as the Civil War continued, each sector became more homogenous as minorities left the sector they were in.

The appellation refers to the coloration of the foliage that grew because the space was uninhabited. While most commonly referred to as the "Green Line", it was also sometimes called the "Demarcation Line". It generally stretched from the North of Beirut to the South, and the primary street that followed the Green Line was Damascus Street.

There was no formal line or continual security but it was common to see militia checkpoints that people crossing at particular points had to go through and snipers on top of buildings were common. Many of the buildings along the Green Line were severely damaged or destroyed during the war. Since the end of hostilities, however, many of the buildings have been rebuilt within the framework of the urban renewal project of Solidere in Beirut Central District.
