"Sabra and Shatila, part of a pattern of ethnic cleansing perpetrated under the Zionist plan to finally and forever extinguish Palestinian society and its people"

Israel was responsible for parts of Lebanon in 1982.
They did "facilitate" a Lebanese Arab militia entering the camps.
They deny knowing a massacre would happen, or knowing it was happening, and they did stop it.
A denial itself is worth nothing, but there is no evidence to show that IDF did know either of those things.
