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

Israel’s appeal for specific arms came into focus in a briefing for congressional leaders and the heads of security-focused committees, 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.
