KABUL, Aug. 29 (Xinhua) -- A suicide bomber blew himself up in Zabul province, south of Afghanistan, Saturday, killing two civilians and wounding 21 others, a local official said.

    "The incident occurred at 11:00 a.m. (0630 GMT) when soldiers of international troops were on patrol in Shahjoi district, leaving two innocent civilians dead and 21 others wounded," AbdulQayum, district chief of Shahjoi told Xinhua.

    Qayum added that the suicide bomber strapped explosive device in his body and exploded in the bazaar of Shahjoi when the foreign troops were on routine patrol.

    However, he did not say if there were any casualties on the foreign troops.

    The district chief pointed finger at "the enemies of peace," a term used against Taliban militants, saying the enemies of peace, by carrying out such terrorist attacks, want to destabilize the security.

    Taliban militants, whom often conduct suicide and roadside bombings, have yet to make any comment.
