Three American service members were killed in a roadside bombing in Afghanistan's eastern Ghazni province, the US military have said.
Three other service members were wounded when an improvised explosive device detonated near the city of Ghazni, the provincial capital, it said.
One American contractor was also wounded.
Lt Ubon Mendie, a spokesman for the US forces, said the wounded service members and contractor were evacuated and are receiving medical care.
The Taliban have claimed responsibility for the attack, saying a US tank was completely destroyed.
They have an extremely active presence in Ghazni province and attempted to take over the capital in August.
Ghazni was the only province that did not hold parliamentary elections in October.
