Ambush or Massacre?

Is 10 a "large number"? I personally think not. In which case this should be renamed to "incident" or "attack" or similar. Otherwise any terrorist attacks that kill 10 or more people should likewise be listed as a "massacre". Wikipedia will quickly fill up with "massacres" diluting those that really are massacre of large numbers of people.    
Agree. Renaming, per the discussion here NoCal100 (talk)

Scorpion pass is referred to as an ambush by the majority.

Morris massacre/terrorist outrage
The strange use of 'massacre' by morris: On the night of 16/17 March ‘infiltrators’ ambushed a civilian bus travelling up Scorpion Pass (Ma’ale ‘Akrabim) on its way from Eilat to Tel Aviv. In the worst terrorist outrage against Israel between 1949 and 1956....Arye Efrat, complained to the government of the desperate security situation; of the burden of guard duty; and of families leaving. He concluded: ‘though nothing like Ma’ale ‘Akrabim has happened to us so far, the way things are going, if no steps are taken immediately, it could end in another such [massacere].

I wonder what the Israeli MFA call it:-
17 Statement to the Knesset by Prime Minister Sharett on the Ma-aleh Akrabim incident- 24 March 1954 Hmmm.

I wonder why NoCal100 has different standards on the word massacre?..
