Palestinian gunmen shot dead six alleged collaborators in the Gaza Strip who "were caught red-handed," according to a security source quoted by Hamas' Aqsa radio on Tuesday. "They possessed hi-tech equipment and filming equipment to take footage of positions," it said.

It did not elaborate. Gunmen chained the body of one of the alleged collaborators to a motorcycle and dragged it throughout the main streets of Gaza City. This was the second time collaborators were reportedly killed in Gaza since the beginning of Operation Pillar of Defense. Palestinian and foreign officials reported Friday that a man, who was killed by gunmen in Gaza, had a banner tied to his neck accusing him in collaborating with Israel and causing the death of 15 Palestinian officials.

"His hands were tied behind his back… they shot his head three times, but he was still alive. Then they turned him on his back and shot him again." The eyewitness also told the New York Times that shortly after the shooting, some 100 men surrounded the man and covered his head with plastic bags. "There were children on the street they should have done it somewhere further away."
