The statement by Western-supported Nur Ad-Din Zanaki rebel group about the killing of the child

Notice the last paragraph of the statement: it says that Syrian regime crimes and the siege of Aleppo has had a negative impact on the psychological state of the rebels.  So whenever they are depressed or stressed, they resort to killing Palestinian children.

PS By the way, remember early on during the Syrian war when American Zionists suddenly feigned concern for the Palestinians in Yarmuk camp? That was classic.
