Since the Israeli military operation against Gaza began July 7, 138 schools have been damaged by bombs, including 89 that are run by the U.N. Relief and Works Agency (UNRWA). Over 400 children were killed and at least 2,000 injured. The situation is exacerbated by the fact that in some instances Hamas has stored munitions in the schools. The UNRWA sites, internationally regarded as neutral, were also used as refuges for people fleeing the fighting, which increased the casualties when these schools were hit (Brookings, August 4).
