Kabul, Afghanistan (CNN) -- A search was under way Thursday for a helicopter belonging to a military contractor, NATO officials said.
The helicopter for Supreme Global Service Solutions went missing Tuesday, said Lt. Col. Todd Vician, a spokesman for the NATO-led International Security Assistance Force.
He did not say how many people were aboard or in what region of the country ISAF was looking for the chopper.
However, the governor of Logar province in eastern Afghanistan said the search's focus has been the Khar Pech district.
Governor Halim Fedia said he did not have any further information. An official with Supreme Global also could not offer additional details.
Authorities did not receive a distress signal from the chopper, Vician said.
"We are using reconnaissance assets to find it. We can't go into more than that. We don't provide detail on ongoing operations," he said.
Supreme Global, based in the Netherlands, provides food supplies for military and multinational forces.
