KABUL, Nov. 24 (Xinhua) -- A suicide bomber, driving a motorcycle, exploded himself near a patrol of the U.S.-led Coalition forces in Afghanistan's eastern province Khost on Saturday, causing no casualties to the troops, police said.

    Wazir Badsha, a police spokesman in Khost province, told Xinhua that the attack took place in Gorbaz district of Khost, in which only one local civilian was injured.

    However, other sources said the civilian was not injured by the blast but by the Coalition forces' firing which followed the explosion.

    There was no immediate responsibility claim for the incident but the Taliban usually carried out such suicide attacks.

    Earlier on Saturday, another suicide bombing attack, apparently targeting the NATO-led International Security Assistance Force, killed 10 people and injured 12 others in Paghman district of Kabul province, the NATO said.

    The war-torn Afghanistan has seen over 600 roadside bombs and 130 suicide attacks since January this year, indicating a 30 percent increase against the same period of last year, according to a UN figure released in mid-October.

    Rising militancy-related violent incidents in Afghanistan have killed over 5,800 people so far this year, hitting a record high.
