Region between the Gulf of Suez and the Gulf of Aqaba (5)

Ross

I believe the answer is:

sinai

(Other definitions for sinai that I've seen before include "place to receive instructions about behaviour" , "11 Across peninsula" , "Ten Commandments mountain" , "Mount on which Moses received the Ten Commandments" , "Mountain in Egypt" .)

I've seen this clue in The Wall Street Journal.
