The Pentagon said Friday it will provide an additional $200 million to Ukraine to boost its security as it struggles with a Russia-backed insurgency.

The funding will go to more training, equipment and military advising so the former Soviet republic can “defend its territorial integrity,” the Pentagon said in a statement. The U.S. has supplied more than $1 billion in security assistance to the country since 2014 when Russia annexed Crimea and backed rebels in eastern Ukraine.
