Russian forces have completed their withdrawal from around Ukraine's capital of Kyiv and the northern city of Chernihiv to consolidate and regroup, said a senior U.S. defense official Wednesday, APA reports citing NBC.
The official said the troops may have left behind mines and Kyiv remains under threat, although the U.S. has not seen any airstrikes there in the last 24 hours.
How long it will take Russian troops to resupply themselves is unknown and will depend on the units themselves and how depleted they are, the official added.
The officials also said the U.S. military is training a small number of Ukrainians inside the U.S., including on how to operate "switchblade" drones.
