Group accuses Israel of firing white phosphorus into Gaza

HRW said the use of white phosphorus in Gaza would violate "the requirement under international humanitarian law to take all feasible precautions to avoid civilian injury and loss of life."

Last week, an Israel Defense Forces spokesman told CNN: "I can tell you with certainty that white phosphorus is absolutely not being used."

Now, however, Israeli officials have a different response to questions about the possible use of phosphorus: "Any munitions that Israel is using are in accordance with international law. Israel does not specify the types of munitions or the types of operations it is conducting."
