Explainer: Why US is stopping some bomb shipments to Israel

President Joe Biden said Wednesday that he would not supply offensive weapons that Israel could use to launch an all-out assault on Rafah — the last major Hamas stronghold in Gaza — over concern for the well-being of the more than 1 million civilians sheltering there. Biden said the US was still committed to Israel's defense and would supply Iron Dome rocket interceptors and other defensive arms, but that if Israel goes into Rafah, “we’re not going to supply the weapons and artillery shells used.”
