The fourth batch of additional US military aid worth $60m has already been delivered to Ukraine. The cargo includes about 80,000 kilograms of ammunition.

"This was the fourth shipment by the United States as part of the $60 million in additional aid that Joe Biden sent to Ukraine in August, demonstrating the United States' commitment to the success of a stable, democratic and free Ukraine," the US Embassy in Kiev said.

The agency recalled that since 2014, the U.S. has provided more than $2.5 billion in military aid to Ukraine.
