Israel accused of using white phosphorus in Gaza

JERUSALEM (Reuters) - A leading human rights group on Saturday accused Israel of using white-phosphorus munitions during its offensive in the Gaza Strip and warned of the risk to Palestinian civilians who live near the fighting.

Human Rights Watch said in a statement that its researchers in Israel observed multiple air-bursts on January 9 and January 10 of artillery-fired white phosphorus near the city of Gaza and the Jabalya refugee camp.

The group said Israel appeared to be using the munitions to make smoke screens to hide military operations -- "a permissible use in principle under international humanitarian law."

But Human Rights Watch said the practice should be stopped in Gaza's densely populated areas.

"White phosphorus can burn down houses and cause horrific burns when it touches the skin," said Marc Garlasco, senior military analyst at Human Rights Watch.

The Israeli army said it would not provide details about the munitions it was using in the Gaza Strip, but it added: "We emphasize that the IDF (Israeli army) only employs weapons permitted by international law."

Israel confirmed in 2006 that it had used phosphorus shells during its war against Hezbollah guerillas in Lebanon.

White phosphorus munitions are not considered chemical weapons. The substance ignites easily in air at temperatures of about 30 Celsius (86 Fahrenheit) and its fire can be difficult to extinguish.

Human rights organizations have long urged a world ban on the munitions, saying they cause undue suffering through severe burns.
