Estimates of deaths in the Libyan Civil War vary with figures from 2,500 to 25,000 given between March 2 and October 2, 2011. An exact figure is hard to ascertain, partly due to a media clamp-down by the Libyan government. Some conservative estimates have been released. Some of the killing "may amount to crimes against humanity" according to the United Nations Security Council and as of March 2011, is under investigation by the International Criminal Court.
