KABUL, Nov. 18 (Xinhua) -- A suicide bomber driving an explosive-laden car targeted a convoy of the NATO-led International Security Assistance Force (ISAF) in Afghanistan's restive Helmand province Sunday, killing himself and damaging a military vehicle, police said.

    "It was 10:30 a.m. local time when the bomber blew his car up next to the NATO convoy in Gereshk district, killing himself and damaging an Armored Personnel Carrier (APC) of the troops," provincial police chief Mohammad Hussain Andiwal told Xinhua.

    However, he said there were no casualties on the ISAF side. Also no civilians were killed or injured in the attack.

    No group or individuals have claimed responsibility for the attack, but Taliban militants who have staged a violent comeback three years ago often carry out such attacks.

    Over 5,700 people have been killed in violence and conflicts so far this year in the war-torn Afghanistan.
