This is what Maan is reporting:
Two Palestinian civilians were killed and four others were injured on Tuesday when Israeli helicopters fired on a group of fighters on the road to the disused Yasser Arafat Airport east of the city of Rafah in the southern Gaza Strip.
What did those civilians exactly do in a group of fighters? Of course the Ezzedeen Alquassam Brigades Information Office mentions only the civilians:
sources reported that the Zionist war planes hit a group of Palestinian civilians east of Rafah city.
Meanwhile the Israel Defense Forces reported:
that IAF jets opened fire at the mortar launching cell and identified a hit.
So whom should we believe? Maybe the Al Quds site:
Eyewitnesses said the “… and they were resistance fighters that fired several motars.”
This sounds really close to the truth.
The 'resistance fighters' ARE civilians, except when they are shooting at you. Naturally, the other side sees them as civilians EVEN when they are shooting at you.
