The American effort to supply Israel with new military assistance took a step forward overnight, as Biden administration officials briefed Congress on weapons the ally is urgently seeking from the United States.

Israel’s appeal for more arms came into focus in a briefing for congressional leaders and the heads of security-focused committees on the surprise attacks by Hamas, according to two people familiar with the meeting. During the unclassified call, officials told lawmakers that America’s closest ally in the Middle East urgently needs precision-guided munitions and more interceptors for the Iron Dome air defense system.

One of the people familiar with the call said Israel is also seeking more U.S.-made small-diameter bombs.
