Saudi city is tourist magnet (5)
I believe the answer is:
mecca
I believe this is a double definition.
'saudi city' is the first definition.
(I've seen this in another clue)
'tourist magnet' is the second definition.
(I've seen this before)
'is' acts as a link.
(Other definitions for mecca that I've seen before include "Pilgrim's destination" , "place for pilgrims" , "Mohammed's birthplace" , "Holy city of Islam" , "Holy place of Islam" .)
