DHAYRA — In October, Israel used US-supplied white phosphorus in an attack on southern Lebanon that injured at least nine civilians, the Washington Post reported. اضافة اعلان

A journalist working for the newspaper found remnants of three 155-millimeter artillery rounds fired into Dhayra, near the Israeli-Lebanese border. White phosphorus fell onto several homes and ignited fires, incinerating at least four homes. It ruined furniture, stripping appliances to scorched metal. Remnants of the sticky, black chemical littered the ground 40 days after the attack and combusted when residents kicked at it.

White phosphorus is a corrosive weapons material that ignites when in contact with oxygen and burns at temperatures up to 1,500 degrees, which can cause severe injuries. The chemical can stick to skin; causing fatal burns, organ failure and respiratory damage. Its use in civilian areas could be prohibited under international humanitarian law, according to the Human Rights Watch (HRW).

Of the nine injured in Israel’s attack on Dhayra, at least three were hospitalized.


Lot production codes found on the shells match the terminology used by the US military to categorize domestically produced weapons. The shells indicate they were manufactured by ammunition depots in Louisiana and Arkansas in 1989 and 1992. The US origin of the shells was then verified by the HRW and Amnesty International as the same manufacturing codes also appear on shells lined up next to Israeli artillery in a photo released on Oct. 9.

The weapons are a fraction of the billions of dollars in U.S. military arms flow to Israel every year, which is also backing Israel’s war on Gaza. At least 20,000 Palestinians have been killed since the Israeli bombardment began, according to the Gaza Health Ministry.

Following the breaking of this news, National Security Council spokesman John Kirby said the Biden administration is “concerned” about the use of white phosphorus and that they would be “asking questions to try to learn a bit more.”


Tensions have risen between Israeli Occupation Forces (IOF) and Hezbollah along Lebanon’s southern border in the weeks since Oct. 7.

Dhayra, a town of 2,000 people, has become the stage for the aggression. Now, at least 94 people have been killed on Lebanon’s side of the border according to data released by the Lebanese Health Ministry. 82 of which were Hezbollah fighters. While at least 11 Israelis have been killed, most of them soldiers.

Dhayra residents speculated that the phosphorus was meant to displace them from their village and to clear the way for future IOF activity in the area.

The IOF wrote that white phosphorus shells launched by Israel are used to create smokescreens, obstructing enemy vision, not for targeting civilians or causing fires. It said its use of the weapon “complies and goes beyond the requirements of international law.”


However, the Washington Post reported that the IOF possess safer alternatives, such as M150 artillery rounds, which smokescreens without the use of white phosphorous.

The US is responsible to track the behavior of its allies who receive its military assistance, assuring they comply with US and humanitarian law, experts said. According to humanitarian law, the use of white phosphorus is permitted if used for legitimate military operations, but its abuse is deemed a war crime.

“The fact that US-produced white phosphorus is being used by Israel in southern Lebanon should be of great concern to US officials,” wrote Tirana Hassan, the executive director of the HRW. “[Congress] should take reports of Israel’s use of white phosphorus seriously enough to reassess US military aid to Israel.”

The US is not conducting real-time assessments of Israel’s adherence to the laws of war. “Anytime that we provide items like white phosphorus to another military, it is with a full expectation that it’ll be used in keeping with...legitimate purposes and in keeping with the law of armed conflict,” Kirby said.

It is unclear when the US delivered the weapon to Israel. According to Pentagon spokesman, Pat Ryder, the U.S. has not provided white phosphorus munitions to Israel since Oct. 7.


“When it comes to our relationship with Israel, we’ll continue to communicate to them the importance of mitigating civilian harm,” Ryder said.

In 2013, the Israeli military pledged to stop using white phosphorus on the battlefield, saying it would transition to gas-based smoke shells.

However, Israel’s empty promises pile as they used the phosphorus more than 60 times in southern Lebanon in the past two months, according to data collected by war monitor group, ACLED.

Lebanese Prime Minister Najib Mikati said on Dec. 2 that Israel’s use of white phosphorus has “killed civilians and produced irreversible damage to more than 5 million square meters of forests and farmland, in addition to damaging thousands of olive trees.”
