Russia warns US of 'unpredictable consequences' amid latest arms shipment to Ukraine: report

Russia warned the U.S. and NATO this week that there could be "unpredictable consequences" if they continue to send Ukraine "sensitive" weapons as it prepares to launch a massive ground offensive in eastern Ukraine, a report said Friday.

The Biden administration announced that another $800 million in security assistance would be sent to Ukraine Wednesday, including artillery, coastal defense drones, anti-aircraft and anti-tank armored vehicles, and Mi-17 helicopters. 

Pentagon press secretary John Kirby said the defense systems approved by the U.S. are "reflective of the kind of fighting that the Ukrainians are expecting to be faced with" as Russia focuses on eastern Ukraine. 

The announcement came one month after President Biden had approved a separate $800 million arms package for Kyiv.
