See skeptical post by As'ad AbuKhalil, who questions HRW's balance, as well as noting inconsistenly in how HRW describes indiscriminate shellin.
Also noteworthy are the comments of UN Secretary General Ban:
“I am just appalled,” he said on visiting the UN Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) compound that was bombed by Israel last week. “Everyone is smelling this bombing still. It is still burning. It is an outrageous and totally unacceptable attack against the United Nations.
“I have protested many times, and am today protesting in the strongest terms, and am condemning it. I have asked for a full investigation and to make those responsible people accountable.”
