It is undisputed that Hamas was using at least part of the compound to shelter terrorists.
Due to Hamas persecution, the scarce population of Christians in Gaza (about 3,000 in 2007, down from something like 50,000 decades ago) is down to somewhere in the 800-1500 range.
Some of the few Christians left were, indeed, sheltering there, but Hamas loves its human shields and so also puts its people there.
And more than half of FR.
