United Nations compounds in Gaza were hit with such munitions, according to the BBC, but the IDF says all attacks were in accordance with international law, and an internal investigation is being started.
In the meantime, (yet unsubstantiated) claims are coming from a mother describing how her children "melted" in front of their eyes when hit with such munitions. Unexploded white phosphorus bombs leak the corrosive substance into the streets and buildings of the Gaza Strip.
It seems not enough that their children are being decapitated in front of their eyes by conventional weapons.
It is evident that some dead are worth more than others.
