KABUL, July 24 (Xinhua) -- Unknown men attacked the house of a government employee in southeast Afghanistan's Khost province with hand grenades, killing four persons and wounding four others, a local official said Monday.

    Unidentified militants threw several hand grenades on the house of Wazir Gul, the director for communication of Yaqubi district, Sunday night, killing four persons including his three daughters, the district chief of Yaqubi Mirza Jan Mangal told Xinhua.

    Four more persons, including Wazir Gul, were also wounded in the attacks.
