Estimates of deaths in the 2011 Libyan vary with figures from 15,000 to 30,000 given between March 2 and October 2, 2011.[1] 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[2] and as of March 2011[update], is under investigation by the International Criminal Court.[3]
