Baghdad, Iraq (CNN) -- A U.S. soldier died Sunday from injuries sustained by enemy small arms fire, the military said in a statement.
The soldier was conducting advisory operations in northern Iraq, according to U.S. Forces. The person's name was being withheld pending notification of relatives and release by the Defense Department.
The incident was under investigation, officials said.
It marks the third hostile death during Operation New Dawn, which began September 1 as officials declared the end of combat operations in Iraq. As part of the operation, U.S. forces remaining in the country are expected to switch to an advise-and-assist role.
In all, 11 soldiers have died in Operation New Dawn, most of them from non-combat incidents, including vehicle crashes.
Two soldiers died September 7 after they were hit with small arms fire inside an Iraqi Army commando compound.
