The Gaza Strip is a Palestinian exclave on the eastern coast of the Mediterranean Sea, bordered by Egypt on the southwest for 11 km (6.8 mi) and Israel on the east and north along a 51 km (32 mi) border. It is densely populated and impoverished, in part due to the presence of large numbers of Palestinian Arab refugees living in extreme poverty in squalid camps. The majority of Palestinians in the Gaza Strip are descendants of refugees who fled or were expelled from what is now Israel during the 1948 Arab-Israeli War. The Gaza Strip is part of the localized Israeli-Palestinian conflict, but is also a scene of power struggle between regional powers including Egypt, Iran, and Turkey together with Qatar, supporting different sides of the conflict. Israel largely provides and controls Gazas water supply, electricity, and communications infrastructure, and according to Human Rights Watch and Amnesty International, Israel remains an occupying power under international law. Palestinians living in the Gaza Strip are under military occupation and are regularly subjected to violence by Israeli settlers and security forces, including deadly escalations, including regular aerial bombardments of the Gaza Strip.
