Did I Miss Something?

I intend to write a long post on Israel soon, but until then this one will have to suffice. So apparently there's a ceasefire in the Gaza Strip, which Palestinian groups routinely violate by firing rockets into Sderot. So it makes sense that the Palestinians are responsible for violating the ceasefire, right?

"PLO executive committee member Yasser Abed Rabbo, who also serves as an advisor to Abbas, warned that the Israeli decision would lead to the breakdown of the cease-fire. He described the decision to target Kassam launchers as a "breach" of the cease-fire agreement."

Huh?

Basically they can shoot at Israel but if Israel retaliates, the Israelis are breaking the ceasefire?!
