A suicide bomber attacked NATO troops in a suburb of Afghanistan's capital Kabul Sunday afternoon, causing no casualties, an official at the press department of Afghan Interior Ministry said.
"Today at 2 p.m. local time a suicide bomber driving an explosive-laden car detonated his vehicle in Khirabad village of Charasiab district south of Kabul when a convoy of NATO forces was passing though," the official told Xinhua but he declined to be identified.
The bomber, he added, was killed in the explosion while there were no causalities on NATO forces.
Meanwhile, a spokesman of NATO troops here confirmed the explosion and declined to say if there were any casualties by saying investigation is underway.
More than 200 people, mostly militants, have been killed so far this year in Afghanistan while militancy had claimed more than 4, 000 lives in 2006.
Taliban leader Mullah Mohammad Omar has vowed to intensify attacks this year.
