Once again, Palestinians have executed one of their own. No trial. No justice. Just a shot to the head. This practice is now well-known in the West Bank and Gaza. From the BBC today:

Gunmen in the Gaza Strip have killed a Palestinian man they suspected of collaborating with the Israelis as he was being treated in hospital. The man, named as Mahmud al-Sharif, had been injured when a grenade was flung into his jail cell by a policeman.

At least six prisoners were injured in the grenade attack at the strip's main jail in Gaza City.

Four of those hurt were accused of collaborating with Israel, Palestinian security officials said.

Police said homemade grenades were thrown into sleeping quarters.
