In 1967, as a result of the Six-Day War, Israel captured and occupied the West Bank, including East Jerusalem, the Gaza Strip and the Golan Heights. Israel also captured the Sinai Peninsula, but returned it to Egypt as part of the 1979 Egypt–Israel peace treaty. Between 1982 and 2000, Israel occupied part of southern Lebanon, in what was known as the Security Belt. Since Israel's capture of these territories, Israeli settlements and military installations have been built within each of them, except Lebanon.
