I want to know the answer to the following question:
What position was held by Gaddafi's brother-in-law?
All the background I'm provided with is that "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.". Is that enough to answer the question?
Answer: yes
