The war began with a surprise joint attack by Egypt and Syria on Yom Kippur, the Jewish day of atonement. Egypt and Syria crossed the cease-fire lines in the Sinai and Golan Heights, respectively, which had been captured by Israel in 1967 during the Six-Day War. OPEC limits the out flux of crude oil to world markets in response.
