BEIRUT (AP) — By his own account, Abu Wadiyeh is a man very much in demand.

One look at the jumbled mass of sinewy electricity cables, TV and Internet lines that droop over the damp, narrow alleyways of the Palestinian refugee camp of Shatila, and it’s easy to see why. Abu Wadiyeh, as the chief electrician in Shatila, is responsible for making order out of that chaos and ensuring that the camp’s more than 20,000 residents can turn on their lights and televisions.
