KABUL, Feb. 10 (Xinhua) -- Two contracted civilians of the NATO- led ISAF coalition were killed in a suicide bomb attack earlier Monday in Afghanistan capital of Kabul, the coalition forces confirmed in a statement.
"Two International Security Assistance Force contracted- civilians died as the result of a vehicle-borne improvised explosive device attack in eastern Afghanistan today," the statement said.
The brief statement gave neither the nationalities of the victims nor the details about the incident under the ISAF policy.
Following the blast, Hizb-e-Islami led by Gulbudin Hekmatyar, the second militant group fighting government forces and the NATO- led coalition troops claimed the responsibility for the attack.
The bombing occurred at around 2:30 p.m. (local time) after a suicide bomber rammed his explosive-laden car to an ISAF convoy in Mahbass square near a main prison in eastern edge of Kabul.
The blast also damaged one vehicle of the convoy and a civilian car besides, smashing the windowpanes of the nearby houses.
More than 57,000-strong NATO-led foreign troops, with 38,000 of them Americans, are currently being deployed in Afghanistan. The majority of them will leave the country before the end of the year.
