I thought I'd do a quick search on the use of the word "massacre".
1. Abbas Condemns Israeli Massacre
Beirut, Nov 1 (Prensa Latina) Palestine s President Mahmud Abbas reacted angrily to the killing of six people by the Israeli soldiers who attacked Gaza Strip late Tuesday and early Wednesday.
2. Israeli occupation forces remain in Beit Hanoon after massacre that killed seven Palestinians
PNN, (Gaza City) Wisam Afifeh Tuesday, 24 October 2006
The day after the massacre that claimed the lives of seven Beit Hanoon residents and injured scores more, Israeli forces continue to occupy the northern Gaza Strip town. Eyewitnesses report that Israeli occupation tanks surround the town on all sides and that troops have taken to bulldozing nearby agricultural land.
And this goes on and on.
Seems everything Israel does is nothing short of a "massacre".
