On the evening of 28 April 2003, a crowd of about two hundred people defied a curfew imposed by the Americans and gathered outside a secondary school used as a military HQ to demand its reopening. Soldiers from the 82nd Airborne stationed on the roof of the building fired upon the crowd, resulting in the deaths of 17 civilians and the wounding of over 70. American forces claim they were responding to gunfire from the crowd, while the Iraqis involved deny this version. Human Rights Watch also dispute the American claims, and says that the evidence suggests the US troops fired indiscriminately and used disproportionate force. A protest against the killings two days later was also fired upon by US troops, resulting in two more deaths.
