Not even Israel has been able to come up with reports of militants being killed in any numbers - none at all, just vacuous claims like tihis one.

Yes they have.

"The Israel Defense Forces cannot refute the images of dead women and children that are broadcast abroad, so instead the army is trying to construct a narrative proving that its targets — and the aftermath of its attacks — are legitimate.

The Meir Amit Intelligence and Terrorism Information Center is a vital partner in constructing this narrative. The center, which is checking the name of each Palestinian said killed in the Gaza fighting (it has gotten to 450 so far), estimates that some 46 percent of them are "terrorist operatives." This figure may change in accordance with further investigation.

The center's lists are accompanied by photographs of posters and death notices of some of the militants. Each name is marked "non-involved," "unidentified" or "terrorist operative." The source for the information of each person's "involvement" is not mentioned, apart from operatives whose photograph appears in death notices or public reports of the militant organization to which he belonged"
