Right-wing parties are angered by the prosecution's decision to set up an independent commission to probe the assassination of Hamas commander Salah Shehadeh five years ago in an airstrike on his Gaza home that left over a dozen civilians dead.
"Combat pilots will be scared to step out of their aircraft for fear of the legal commission awaiting them," National Union-NRP MK Effie Eitam said.
Israel Our Home MK Israel Hasson suggested that members of the commission be sent to the Qassam-stricken town of Sderot carry out the probe.
The State Prosecution told the High Court on Monday it would set up a commission to investigate whether criminal charges should be brought against officials involved in the decision to carry out the assassination in response to a petition by the peace organization Yesh Gvul.
Shehadeh died in June 2005 when an IAF aircraft dropped a one-ton bomb on a neighborhood in Gaza city, killing 15 innocent civilians mainly women and children.
"There should be an investigation to determine whether the decision was negligent and whether it was possible to foresee the unforgivable harm to innocent toddlers and women," the petitioners wrote.
"The State of Israel should set up a commission of inquiry the day when Hamas sets up its own commission to find out how it can succeed to kill as many innocent Jews in one day," Hasson added.
"On the eve of Yom Kipur I would have expected those who filed the foolish petition to indulge in introspection in memory of the victims who died because of Shehadeh," Hasson said.
Eitam said the operation was already investigated by internal IDF committees and there was no need for an independent investigation.
Labor MK Danny Yatom, the former head of the Mossad, said the prosecution agreed to set up the commission once it realized that the High Court would not backtrack on it ruling that the investigation carried out thus far are insufficient.
"In the past many operations were cancelled because innocent civilians were likely to get killed. But at other times it is known that there is a chance civilians will be harmed but considerations lead to authorizing the dropping of a bomb," Yatom said.
