In several public appearances, Gaddafi threatened to destroy the protest movement, and Al Jazeera and other agencies reported his government was arming pro-Gaddafi militiamen to kill protesters and defectors against the regime in Tripoli. Organs of the United Nations, including United Nations Secretary General Ban Ki-moon and the United Nations Human Rights Council, condemned the crackdown as violating international law, with the latter body expelling Libya outright in an unprecedented action urged by Libya's own delegation to the UN. The United States imposed economic sanctions against Libya, followed shortly by Australia, Canada and the United Nations Security Council, which also voted to refer Gaddafi and other government officials to the International Criminal Court for investigation.
