https://en.wikipedia.org/wiki/Green_Line_(Israel)

The Green Line is often referred to as the "pre-1967 borders" or the "1967 borders" by many international bodies and national leaders, including former United States president Barack Obama,^[6] Palestinian president Mahmoud Abbas,^[7] the United Nations (UN) in informal texts,^[8] and in the text of UN General Assembly Resolutions.^[9] The name comes from the green ink used to draw the line on the map during armistice talks.^[10] After the Six-Day War, the territories captured by Israel beyond the Green Line came to be designated as East Jerusalem, the West Bank, the Gaza Strip, and the Golan Heights. These territories are often referred to as Israeli-occupied territories. The Sinai Peninsula, which was also captured at that time, has since been returned to Egypt as part of the 1979 peace treaty.
