A triangle-shaped peninsula in Egypt, located between the Mediterranean Sea and Red Sea. The Suez Canal runs along the northwestern edge of the peninsula. It was a strategic location in the Wars of 1956, 1967 and 1973. Captured by Israel in 1967, Israel returned the peninsula to Egypt in 1979 in exchange for bilateral peace between the two countries (see Israeli-Egyptian Peace Treaty).  http://www.justvision.org/glossary/sinai-peninsula
