The body of a Palestinian man was delivered to a hospital Monday, a week after he was abducted by Hamas operatives in what appeared to be a new case of vigilante justice by the group following its takeover of the Gaza Strip. Mahir Abu Dhalfa, 45, was nabbed last week by Hamas's Executive Force in Gaza City. Early Monday, his body was brought to Shifa Hospital with signs of suffocation, Palestinian medical officials said. Abu Dhalfa was not known to be affiliated with any group, but his brother belongs to the Popular Front for the Liberation of Palestine, a small, radical group, and is sitting in a Hamas prison, relatives said. Hamas officials couldn't immediately be reached for comment on the incident.
