Mossad in tangle with Arab diplomat (10)

I believe the answer is:

ambassador

'diplomat' is the definition.
(ambassador is a kind of diplomat)

'mossad in tangle with arab' is the wordplay.
'in tangle with' indicates an anagram.
'mossad' with its letters anagrammed with 'arab' gives 'AMBASSADOR'.

(Other definitions for ambassador that I've seen before include "High-ranking diplomat" , "Overseas envoy" , "voice?" , "Messenger" , "foreign agent" .)

I've seen this clue in The Telegraph.
