The NATO-led International Security Assistance Force had said late on Monday that a US Department of Defense civilian employee had died that day in eastern Afghanistan.
The force confirmed on Tuesday that the man had died in Kabul, and was an engineer. They declined further comment.
Security is tight in Kabul, even though violence is rising across other parts of the country, and it is rare for a foreigner to go missing in the capital.
The Taleban struck last month when they raided a British cultural center in Kabul on the 92nd anniversary of Afghanistan’s independence from British rule. Nine people were killed during the hours-long assault.
Afghan forces have had responsibility for security in the city since 2008, but there are many NATO forces stationed in and around the capital, and they are regularly called on to help during complex attacks.
