Includes facilities underneath the hospital.
At the time of market creation (October 30th).
However if it's clear it was used as a command centre but unclear whether this had stopped by 30th of October or not, will resolve YES.
Resolution criteria:
I will make a judgement based on arguments in the comments and a critical reading of many sources, including the following:
Post war report from amnesty international
Eg: https://www.amnesty.org/en/documents/mde21/1178/2015/en/
Findings from Isreal's Military Advocate General's Corps
More about them here: https://en.m.wikipedia.org/wiki/Military_Advocate_General
Eg: https://www.idf.il/en/mini-sites/military-advocate-general-s-corps/mag-corps-press-release-update-2-dec-2014
Open source intelligence analysis
Official Palestinian reports
Offical reports from other governments
Market resolution goes based on what I expect the median informed, intelligent person reading the same evidence would come away with.
If I judge there is not a preponderance of evidence pointing one way or another, I'll resolve NA.
I may change the criteria to make them better in response to suggestions.
