The Al-Mezan Center for Human Rights has counted the Gaza dead from last Sunday to today, and counts 160 people. This is higher than I had counted - I was at 146 including some West Bank murders as well. So the revised total is now 289 (my count as of last Sunday morning) +160+3 West Bank deaths I've documented+5 dead civilians that Hamas killed but blamed on Israel=457 killed this year by each other.
They also count 769 injuries.
UPDATE: Another execution of a Hamas dude by Fatah in the West Bank. 458.
UPDATE 2: "Popular Resistance Committees" shoot at PalArabs waiting at the Erez crossing, killing one. PalArab media uniformly and wrongly blames Israel. 459. (Fatah also claimed that Hamas executed 5 in Gaza this morning, but I could find no corroboration.)
UPDATE 3: PalArab murdered Wednesday, arriving at a hospital with multiple gunshot wounds. 460.
UPDATE 4: A second executed today. Wafa mentioned two dead today. It is very interesting that Wafa has this news and Ma'an does not. 461.
