WASHINGTON - Three US soldiers were killed due to a roadside bomb explosion in eastern Afghanistan, The Washington Post reported on Tuesday.

Citing US military officials, the report said that the incident took place during a US military patrol near Ghazni city, which caused three other US service members and a US military contractor wounded.

The survivors were evacuated from the area and received medical attention, according to the report.

The official website of NATO Resolute Support Mission in Afghanistan confirmed the casualties in this attack on Tuesday.
