Query: What position was held by Gaddafi's brother-in-law?
Context: On 27 June, the ICC issued arrest warrants for Gaddafi, his son Saif al-Islam, and his brother-in-law Abdullah Senussi, head of state security, for charges concerning crimes against humanity. Libyan officials rejected the ICC, claiming that it had "no legitimacy whatsoever" and highlighting that "all of its activities are directed at African leaders".
