The U.S. began sending Ukraine longer-range Army Tactical Missile System (ATACMS) missiles last month and "will send more now that we have additional authority and money," National Security Adviser Jake Sullivan said.

The ATACMS missiles were fired by Ukraine for first time last week and more are coming in a new US aid package, officials say

The 2,300mph ATACMS were used last week in a caught-on-camera strike on a Crimean air base, destroying valuable ammunition in storage.
