When modern Islamic countries gained their independence in North Africa, often following serious warfare (such as during the Algerian War of Independence against the French), the Arab-Israeli conflict became the main focus of significant battles. During the 1973 Yom Kippur War, the Egyptian army broke through the Bar Lev Line, invading the Israeli-held Sinai Peninsula, resulting in UN cease-fire after United Nations Security Council Resolution 338, 339 and 340, which finally led to strategic and political gains for Egypt and Israel.
