A United Nations inquiry into attacks by Israeli forces on UN property during the Gaza conflict four months ago has heavily criticised Israel's army, BBC reported.
It found Israel to blame in six out of nine incidents when death and injuries were caused to people sheltering at UN property and UN buildings were damaged.
In one case, Palestinian militants were found to have fired at a UN compound.
The UN recommends further investigation into possible war crimes. Israel has branded the report "highly unbalanced".
The investigation rejects Israel's claim that militants were firing from the Fakhura school when at least 40 people outside the school were killed in Israel shellfire.
It also criticises Israel's use of white phosphorous shells which caused the incineration of UN's main food warehouse in Gaza - something the UN says showed "reckless disregard" for civilian safety.
The Israeli foreign ministry said UN investigators had ignored evidence given by Israel and had sided with the Palestinian Hamas movement.
