American becomes a rebel with a cause in east Ukraine

YASYNUVATA Ukraine (Reuters) - With his face hidden behind a camouflage balaclava and an assault rifle slung over his shoulder, "Hunter" looks like other separatist fighters in eastern Ukraine.

What distinguishes him from his brothers in arms in the Vostok (East) battalion, an irregular pro-Russian militia fighting government forces, is his American accent - and English is the only language he knows.
