Prosecutors at the International Criminal Court requested arrest warrants Monday for Moammar Gaddafi, his son Saif al-Islam Gaddafi and Libyan intelligence chief Abdullah Senussi, saying all three had committed crimes against humanity in the killings of Libyan protesters over the past three months.

The request, accompanied by a 74-page dossier detailing the alleged crimes, was bolstered by information from “high-level officials in Gaddafi’s regime” who contacted The Hague in the past week, prosecutors said.

“The evidence shows that Moammar Gaddafi personally ordered attacks on unarmed Libyan civilians,” chief prosecutor Luis Moreno Ocampo said. “We have such strong evidence, direct evidence of their involvement in the crimes,” he said of Gaddafi, his son and the intelligence chief. He called Senussi an “executioner.”
