What is a human shield and how has Hamas been accused of using them?

That's what chicken shniznit terrorists do. They use human shields cause they know our morals and LOAC will not allow us to engage those targets.

..."What is the definition of a human shield?
The international criminal court defines the war crime of using human shields as “utilising the presence of a civilian or other protected person to render certain points, areas or military forces immune from military operations”.

One interpretation of this is that it would be a war crime to fire weapons and to position bases in proximity to heavily populated civilian areas, in particular near facilities that should be protected according to the Geneva conventions, including schools, hospitals or mosques.

During conflicts against Hamas and other armed militant groups in Gaza, Israel has repeatedly accused them of deliberately shielding themselves behind Gaza’s civilian population."...

It's already been confirmed that Hamas is using human shields and facilities against the stipulations outlined in the LOAC, as we have all been trained not to do in warfare. Rather than question it at this point, it should be denounced by all. Regardless of their feelings to the Palestinians. Especially since it is the Palestinians who suffer the most at this point because of Hama's actions.
