KABUL, May 29 (Xinhua)-- Taliban insurgents fighting Afghan and the U.S.-led forces in Afghanistan, attacked a supplying convoy in the southern Zabul province, killing four drivers and set on fire 10 trucks, provincial police chief Abdul Rahman Sarjang said Friday.

    "A group of Taliban militants attacked a convoy of trucks in Shinkai district Thursday evening, killing four truckers and burning 10 trucks," Sarjang told Xinhua.

    All the victims were Afghans, he said.

    He said that the trucks belonged to locals and supplied non-military logistic items to the international troops stationed in south Afghanistan.

    Troops from several countries including the U.S., Canada, Australia, Britain and Holland have been serving in the southern region to stabilize security there.

    Meantime, a Taliban purported spokesman Qari yusuf Ahmadi in talks with media from an undisclosed location claimed that 15 drivers and guards of the convoy were killed in the attack.

    Taliban fighters have vowed to intensify attacks and activities this year in Afghanistan.
