Attacks on schools during conflict is one of the six grave violations identified and condemned by the UN Security Council. 
The six grave violations form the basis of the Council’s architecture to monitor, report and respond to abuses suffered by children in times of war. Attacks on schools is a trigger to list parties to armed conflict in the annexes of the annual UN report on children and armed conflict.

In the report A/HRC/59/26, the relevant UN Commission wrote that Israeli attacks on educational, religious and cultural sites in the Occupied Palestinian Territory amount to war crimes and the crime against humanity of extermination.

However, we did not look into the whole of the matter but who the victims are to classify each attack as one of those as defined in the Genocide Convention. See Tab 4 on the front page of our website.

The Israelis are systematically claiming that Hamas was among the people without providing any evidence of authentic nature showing that selecting and targeting of more than one person was of legitimate military objective. We do not consider Israeli and pro-Israeli social media posts as evidence, but official documents verified on the ground by independent parties and confirmed. 

Based on this Israeli action, GLOSM/PARES has decided to treat all information found as "war crime as part of 'Killing members of a group' as defined in the Genocide Convention, confirmed by viewing" as long as the Israelis do not allow anyone from outside, and who does have no relation to the parties involved, to verify.
