Amnesty International called Tuesday on the Hamas administration in the Gaza Strip to end its "deadly deadly campaign of abductions, deliberate and unlawful killings, torture and death threats" against alleged collaborators with Israel, and other opponents, dpa reported.
In a statement to the media, the human rights group said at least 24 men have been shot dead by Hamas gunmen, and scores of others have been shot in the legs, or kneecaps, or injured in some other ways meant to inflict severe disability.
The Hamas campaign was carried out during and after the three-week Israeli military offensive against militants in the Strip, which lasted from December 27 to January 18.
Amnesty said in its statement that a fact-finding team, which visited the salient during and after the Israeli offensive, recorded testimony "from a number of victims, as well as medical sources and eyewitnesses who were able to corroborate their stories."
Others, said the organization, were afraid to speak out for fear of retribution.
"Amnesty International is calling on the Hamas de-facto administration to immediately end the campaign of abuses and to agree to the establishment of an independent, impartial and non-partisan national commission of experts to investigate them," the statement said.
