Fort Riley ? Two 1st Infantry Division soldiers from Fort Riley have died of wounds they suffered in separate attacks in Afghanistan.

Officials at the northeast Kansas post say 26-year-old Staff Sgt. Matthew Stiltz, of Spokane, Wash., was killed Monday during an insurgent attack in the Zerok district.

On Friday, 37-year-old Capt. James D. Nehl, of Gardiner, Ore., died in eastern Afghanistan’s Ghanzi Province.

Fort Riley officials announced the two deaths Tuesday.

Stiltz was a member of the 1st Battalion, 28th Infantry and had been at Fort Riley since 2006. It was his first deployment to Afghanistan after two deployments to Iraq.

Nehl was with the 2nd Battalion, 16th Infantry and had been at Fort Riley since May. He served previously in Iraq and was on his first deployment to Afghanistan.
