The United States has secretly shipped a small number of surface-to-surface missiles to Ukraine in recent days to provide Kiev with a long-range strike capability against Russian forces amid the ongoing counteroffensive, the report said.
The versions of the ATACMS that were provided have a range of about 100 miles (160 km).
The US has not formally announced the transfer of the longer-range missiles.
Meanwhile, another US newspaper reported that the version of the Army Tactical Missile Systems (ATACMS) that the United States delivered to Ukraine is equipped with cluster munitions.
The United States provided the Ukrainian military a small number of ATACMS missiles, the report said citing a Biden administration official.
Earlier, the Russian Defense Ministry confirmed the ongoing development of a missile system capable of countering ATACMS.
