The US Defense Department says a soldier has died after a vehicle accident that occurred in Afghanistan.

The DOD said Saturday the soldier was supporting Operation Freedom Sentinel, part of the NATO-led mission fighting militants in that country.

Spc. Vincent Sebastian Ibarria, 21, from San Antonio, died as the result of a vehicle rollover accident on Friday in Farah, Afghanistan. The incident is under investigation.

Ibarria was the ninth U.S. service member to die this year in Afghanistan — two were killed in an apparent insider attack, two were killed when their vehicle struck an improvised explosive device, two died in a plane crash and two died in non-combat incidents.
