If they were taken accidentally, they would have better prospects. As in my previous post I don't know if they were targetted intentionally or not.
In the past when the Hamas terrorists have taken hostages it was very few people and they demanded a massive price for release.
With so many hostages now, we're in an unprecedented zone, and it's very hard to predict the odds of hostage survival.
They will of course be spread out and used as human shields.
That's how Hamas rolls.
So if you're religious probably time to pray for them.
