Rights group blasts Hamas for lack of probe into slayings of suspected Israel collaborators

An international rights group has condemned Gaza's Hamas rulers for failing to investigate the public slayings of seven Palestinian men accused of collaborating with Israel.

Human Rights Watch says Gaza's Prime Minister Ismail Haniyeh had promised an investigation into the deaths.

The New York-based group says that four months after masked Hamas gunmen killed the suspects and dragged their bodies through the streets, Gaza's authorities have done nothing to address the murders.

The men had been imprisoned in Gaza but were apparently handed over to the Hamas gunmen during a November bout of fighting between Israel and Palestinian militants. The men were paraded into a public square, accused of aiding Israel and shot.

Islam Shahwan, spokesman for Hamas' Interior Ministry in the Gaza Strip, had no comment on HRW's charges.
