After months of investigation, the Israeli Defense Forces (IDF) released a report addressing accusations from some humanitarian groups that its use of white phosphorus (WP) munitions in the Gaza War was a violation of international law, as the report distinguishes between the use of WP as a weapon and the more common non-weapon purposes such as providing smoke screens to conceal troop movements. The pro-Israel group CAMERA recently quoted from the report in the article, "Did Israel’s Use of White Phosphorus Constitute a War Crime?" by Steven Stotsky, on its Web site. The report not only argued that the military's decision to explode the munition in the air was safer for civilians than it would have been to explode it on the ground, but it also suggested that the use of WP to facilitate troops movements also meant civilian casualties were lower than they otherwise would have been by making attacks on Hamas more accurate.

Last January, evening newscasts and some morning newscasts on the broadcast networks and on CNN and FNC reported on accusations from humanitarian groups – with varying degrees of accuracy – with CBS even referring to WP as a "banned weapon," and a "horrific new weapon, " and contending that the IDF may have committed "war crimes." At one point, CNN similarly incorrectly identified WP as a "banned substance." ABC showed a clip of a wounded Palestinian boy charging that Israelis have "no mercy" even for children. (MSNBC does not have a morning or evening newscast equivalent to NBC’s Today show or the NBC Nightly News, so MSNBC coverage was not examined.) But, according to a Nexis search, none of these news programs showed any interest in updating viewers once the Israeli military had made public its say on the matter.

As previously documented by NewsBusters, the January 22 CBS Evening News ran a report (video here), introduced by anchor Katie Couric, which left the impression that the Israeli military had used a "banned weapon," without informing viewers that there are non-weapon uses for WP, and passed on accusations of "war crimes." Couric: "Hamas just ended a bloody war with Israel in Gaza, and tonight there is growing evidence the Israelis may have used a banned weapon. Some even accuse them of war crimes."

On the January 25 World News Sunday on ABC, as he introduced a report by correspondent Simon McGregor-Wood, anchor Dan Harris played up complaints against "both sides" in the war, and even suggested that the Israeli side may have been worse in its conduct of the war as he highlighted that there was "especially tough criticism" leveled at Israel. Harris: "Both sides are being dogged now by complaints that they violated the rules of war. Israel has come under especially tough criticism for its use of a chemical agent."
