Yes Hamas claim of 1000 soldier dead should be used since it is the newest and the 161 figure is outdated.
both IDF and HAMAS claims of how much they killed from the other side are estimates and of course both of them are inflated and ridiculous , but since it is attributed to them and not stated as a fact but rather as a claim it must be included and i will include it no matter what others do even if i keep adding it daily for one year , i have a very long breath.

If you dont want HAMAS claims so change the title to THE ISRAELI NARRATIVE OF THE 2014 ISRAEL-GAZA CONFLICT.
HAMAS is one of the only two sides of the conflict so not including its claims make the articl out of balance and whatever you feel about them or about palestinians is irrelevant, Imagine if HAMAS were at a justice court wouldnt the judge hear their claims or would he say  listen terrorists i will not hear from you and i will sentence you to so and so.
