WASHINGTON — A U.S. military official says the Pentagon will be deploying a small number of troops to Ukraine to provide medical training to forces there who have been battling Russian-backed separatists.

Between five and 10 service members will go to western Ukraine next week for what will be a second round of coaching and mentoring members of the Ukraine military, who will then go on to become trainers. The official discussed the deployment on condition of anonymity because the official was not authorized to speak on the record.

The U.S. forces will deploy out of Europe.

Last year, the U.S. trained about 300 Ukrainian troops on battlefield medicine.

U.S. officials are continuing to review the range of instruction and other aid that can be provided to Ukraine.

A tenuous cease-fire agreement was reached earlier this month, but there have been repeated accusations of violations of the peace plan.
