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 , is under investigation by the International Criminal Court.
