Ask HN: Good, objective resources on Israeli-Palestinian conflict?

Last night I was arguing with my kids about the Israeli-Palestinian conflict, and I realized I didn't know what I was talking about.

What are some good, reasonably objective resources to understand the history of the conflict and what's going on now?

Surely it's not a clear case of good vs evil, but does either side have the moral high ground? Who did what to whom? How did we get here?

Note: I'll take biased resources as long as the biases are disclosed and I've got a mix of sources.

Thanks.
