The U.S. has received reports of Israel's excessive casualties from US weapons but has taken NO action

The Biden administration has received nearly 500 reports alleging Israel used U.S.-supplied weapons for attacks that caused unnecessary harm to civilians in the Gaza Strip, but it has failed to comply with its own policies requiring swift investigations of such claims, according to people familiar with the matter.

At least some of these cases presented to the State Department over the past year probably amount to violations of U.S. and international law, these people said, speaking on the condition of anonymity because they are not authorized to discuss internal deliberations.

The reports are received from across the U.S. government, international aid organizations, nonprofits, media reports and other eyewitnesses. Dozens include photo documentation of U.S.-made bomb fragments at sites where scores of children were killed, according to human rights advocates briefed on the process.
