She's also the subject of a new CNN mini-documentary. We talk to Moth, as well as her former colleague Stefano Kotsonis, who was in the car with her during the shooting. Kotsonis now works for WBUR.

Palestinians living in the West Bank village of Susiya live in tents and caves with no running water or electricity.

An Israeli humanitarian group, Comet-ME, is now bringing wind and solar power to the Palestinians so they can hold their ground in the disputed territory. We speak to one of the Israeli volunteers of Comet-ME, Yossi Mossel.  Comet-ME is now a finalist for the BBC World Challenge.
