The body of a Palestinian man was delivered to a hospital Monday, a week after he was abducted by Hamas militants in what appeared to be a new case of vigilante justice by the Islamic group following its takeover of the Gaza Strip. Mahir Abu Dhalfa , 45, was nabbed last week by Hamas' Executive Force in Gaza City. Early Monday, his body was brought to Shifa Hospital with signs of suffocation, Palestinian medical officials said. Hamas promised amnesty for its vanquished Fatah rivals in the Gaza Strip, which the Islamic militant group violently seized last month. But since then, at least nine Fatah loyalists have been killed, according to local human rights workers.
