438. Five mortar rounds landed in a crowded area of downtown Sarajevo shortly after 1100 hours on 28 August. Four of the rounds caused only minimal material damage; one round, however, landed in the Markale marketplace, the scene of a similar attack on 5 February 1994. Thirty-seven people, most of them civilians, were killed in and around the marketplace, and approximately 90 were injured. A confidential report to the UNPROFOR Commander concluded that the five rounds had been fired from the Serb-held area of Lukavica, to the west of Sarajevo. (The secrecy surrounding the UNPROFOR investigation into this incident gave rise to speculation, fuelled by the Serbs, that there was doubt as to which side had fired the mortar rounds. A review of United Nations documentation, however, confirms that UNPROFOR considered the evidence clear: all five rounds had been fired by the Bosnian Serbs.)
