Human Rights Watch and the Harvard Law School International Human Rights Clinic have jointly reported Israel’s use of white phosphorus munitions in southern Lebanon. The report, published on Wednesday, September 9th, details an "unacceptable human cost" resulting from this use. Both organizations are calling for a new international treaty to regulate these weapons due to their dangerous effects. The findings raise significant concerns about the legality and proportionality of the munitions’ deployment in a populated area. This report adds to growing international scrutiny regarding the ongoing conflict and the weapons being employed. The organizations urge further investigation into the incidents and accountability for any violations of international humanitarian law.
