The Jerusalem Post has an article on Israeli and Palestinian blogging here (annoying but free registration required) or read it at Renatinha's blog. Mentioned: me, Renatinha, and Gil).

Muhammad Itzhak Shehada Odeh, the Hamas operative who placed the bomb in the Hebrew University cafeteria a couple of weeks ago, worked as a painter/handyman for the University and actually participated in the subsequent cleanup.

The Jerusalem-based Hamas ring of which Odeh is a part also tried to bomb the Pi Glilot fuel depot in Tel Aviv (see these old blog entries: here, here, and here). Most of the ring members are from Silwan, which is known as a "bad neighborhood".
