Thereafter, [[Israel]]i ships were prohibited from using the Canal,<ref>{{cite news |url=http://news.bbc.co.uk/onthisday/hi/dates/stories/july/26/newsid_2701000/2701603.stm |title=1956: Egypt Seizes Suez Canal |publisher=BBC |date=26 July 1956 |access-date=22 January 2015 |archive-date=17 March 2007 |archive-url=https://web.archive.org/web/20070317034109/http://news.bbc.co.uk/onthisday/hi/dates/stories/july/26/newsid_2701000/2701603.stm |url-status=live }}</ref> owing to the state of war between the two states. Egypt also prohibited ships from using Egyptian territorial waters on the eastern side of the peninsula to travel to and from Israel, effectively imposing a blockade on the Israeli port of [[Eilat]]. In October 1956, in what is known in Egypt as the [[Suez Crisis|Tripartite Aggression]], [[Israel Defense Forces]] troops, aided by the [[United Kingdom]] and [[French Fourth Republic|France]] (which sought to reverse the nationalization and regain control over the Suez Canal), invaded Sinai and occupied much of the peninsula within a few days. In March 1957, Israel withdrew its forces from Sinai, following strong pressure from the [[United States]] and the [[Soviet Union]]. Thereafter, the [[United Nations Emergency Force]] (UNEF) was stationed in Sinai to prevent any further conflict in the Sinai.
