While we're on the subject of Palestinian [1] myths, here's another.

"Palestinian groups shell Israeli areas near Gaza despite news of ceasefire," from the [2] Ma'an News Agency (thanks to Sr. Soph):

Gaza – Ma'an – Palestinian military groups continued to launch homemade projectiles and mortar shells into Israel from the Gaza Strip despite news that the factions had agreed during talks in Egypt on a ceasefire.

The military wing of Islamic Jihad, the Al-Quds Brigades, and the military wing of the Popular Resistance Committees, the An-Nasser Salah Addin Brigades, said that their fighters fired barrages of projectiles and mortars at the Israeli cities of Sderot and Ashkelon in the western Negev.

It appears that Palestinian factions are awaiting for the official announcement of a ceasefire before holding their fire....

Yeah, sure, that's it.
