White Phosphorus Controversy: US Expresses Concern as Israel's Alleged Use Intensifies Tensions in Lebanon

 The White House has expressed concern over reports that Israel used US-supplied white phosphorus in attacks on Lebanon. Lebanon had accused Israel of using the incendiary weapon in October, and analysis of shell fragments from one attack showed that the rounds were US-made. While the use of white phosphorus as a chemical weapon is prohibited under international law, it is allowed for illuminating battlefields and can be used as a smokescreen. The United States expects that when it provides white phosphorus to another military, it will be used in accordance with legitimate purposes and the law of armed conflict.

The Washington Post reported that nine civilians were injured in an Israeli attack in southern Lebanon using what appeared to be US-supplied white phosphorus. Remnants of three artillery rounds with serial numbers indicating they were made in the United States were found. The United States is seeking more details on the allegations. The use of white phosphorus is a concern, especially as the conflict could potentially spread to Lebanon, where the Iran-backed Hezbollah group is based. The United States wants to prevent further escalation and ensure that white phosphorus is not used in a way that harms civilians.

The Israeli Defense Minister, Yoav Gallant, stated that Israel acts in accordance with international law. The health ministry in Gaza, however, has been criticized for not distinguishing between civilians and combatants in its reports on casualties from Israeli airstrikes and artillery barrages. UN agencies and the International Committee of the Red Cross have used the health ministry's death tolls in their reports, which have been consistent with the UN's own research into medical records.
