I want to know the answer to the following question:
When did Khamis Gaddafi die?
All the background I'm provided with is that "Together they had seven biological children: Saif al-Islam Gaddafi (b. 1972), Al-Saadi Gaddafi (b. 1973), Mutassim Gaddafi (1974–2011), Hannibal Muammar Gaddafi (b. 1975), Ayesha Gaddafi (b. 1976), Saif al-Arab Gaddafi (1982–2011), and Khamis Gaddafi (1983–2011).". Is that enough to answer the question?
