Gaza fell to British forces during World War I, becoming a part of Mandatory Palestine. As a result of the 1948 Arab–Israeli War, Egypt administered the newly formed Gaza Strip territory and several improvements were undertaken in the city. Gaza was captured by Israel in the Six-Day War in 1967, but in 1993, the city was transferred to the newly created Palestinian National Authority. In the months following the 2006 election, an armed conflict broke out between the Palestinian political factions of Fatah and Hamas, resulting in the latter taking power in Gaza. Egypt and Israel consequently imposed a blockade on the Gaza Strip.
