The State Department has formally notified Congress of a direct sale of 6,500 joint direct action munitions (JDAM) to Israel — while calls for an arms embargo to the government accused of war crimes grow louder.

JDAMs are ostensibly justified as ways for military forces to carry out more precise attacks and “minimize” civilian harm. Meanwhile, such munitions are believed to have been used in the devastating Israeli attack on the al-Masawi tent that killed at least 90 people and injured another some 300.
