Hamas hurls the greatest insult possible to Fatah

In the Al-Qassam Hamas website in Arabic (autotranslated):

Pictures of a number of martyrs who Aleksameen Ela risen to at the hands of Zionists and the Zionists followers from the security apparatus proxy

They are showing the pictures of their dead terrorist member "martyrs" - and saying that the ones killed by Fatah were killed by a proxy for the Zionists.

The picture of the dead guy in the lower left is a nice touch.
