What crimes against humanity did Gaddafi commit?

According to the International Criminal Court at the Hague, the late Libyan leader Muammar Gaddafi was accused of the following:

"The evidence shows that Muammar Gaddafi, personally, ordered attacks on unarmed Libyan civilians. His forces attacked Libyan civilians in their homes and in the public space, repressed demonstrations with live ammunition, used heavy artillery against participants in funeral processions, and placed snipers to kill those leaving mosques after the prayers...

The evidence shows that Gaddafi relies on his inner circle to implement a systematic policy of suppressing any challenge to his authority. His second eldest son, Saif Al Islam, is acting as a de facto prime minister and Al-Sanousi, Gaddafi’s brother-in-law, is his right-hand man and the Head of the Military Intelligence.

The Office gathered direct evidence about orders issued by Muammar Gaddafi himself, direct evidence of Saif Al Islam organizing the recruitment of mercenaries, and direct evidence of the participation of Al Sanousi in the attacks against demonstrators. Additionally the Office documented how the three held meetings to plan the operations.

Muammar Gaddafi committed the crimes with the goal of preserving his absolute authority. As the Guide of the Revolution he has absolute authority in accordance with Libyan law. His orders are binding even for the Congress. It is a crime to peacefully oppose Muammar Gaddafi, insult him or challenge his authority."
