how long was the suez canal closed
Egypt had maintained its state of belligerency with Israel after the armistice agreement was signed. The first manifestation of this was the closing of the Suez Canal to Israeli shipping. On August 9, 1949, the UN Mixed Armistice Commission upheld Israel's complaint that Egypt was illegally blocking the canal. On September 1, 1951, the Security Council ordered Egypt to open the Canal to Israeli shipping.
