HELSINKI, July 28 (Xinhua) -- A Finnish officer commanding the Observer Group Lebanon, part of the UN Truce Supervision Organization (UNTSO), said on Thursday he did not believe that the Israeli airstrike on a UN observation post in Lebanon on Tuesday had been an accident.

    Colonel Rolf Kullberg told Finnish commercial broadcaster Nelonen that prior to the incident, the peacekeepers had repeatedly asked the Israel Defense Forces not to bomb the post.

    Nelonen quoted witnesses as saying that four Israeli warplanes had bombed the post.

    The direct hit on the post killed four UN observers, who were from Austria, Canada, China and Finland. Enditem
