A civilian affiliated with oilfield services giant Halliburton was shot and killed in Iraq, the second person connected to the firm to die in an attack in a month.

The employee, who was not identified, worked for Halliburton subsidiary Kellogg Brown & Root and was assigned to a team supporting Army mail delivery.

The U.S. military in Baghdad confirmed that a U.S. civilian contractor was killed Wednesday in Iraq, but would not offer any details.

An American civilian contractor employed by KBR was killed Aug. 5 when a remote-control bomb exploded under the truck he was driving north of Saddam Hussein’s hometown of Tikrit.

Halliburton, the oil field-services and construction company formerly led by Vice President Dick Cheney, has major contracts for reconstruction in both Iraq and Afghanistan.
