Israel returned the Sinai Peninsula to Egypt in 1982, as part of the 1979 Israel–Egypt Peace Treaty. Although Israel unilaterally disengaged from Gaza in September 2005, it has held the territory under the blockade at various times since June 2007 and is considered the occupying power in the Gaza Strip by the United Nations, the United States, the United Kingdom and various human rights organizations. Israel is considered the current occupying power of the Golan Heights, the West Bank, East Jerusalem and the Gaza Strip.
