I want to know the answer to the following question:
After 2009, who began fighting in Waziristan?
All the background I'm provided with is that "In September 2009, a U.S. Drone strike reportedly killed Ilyas Kashmiri, who was the chief of Harkat-ul-Jihad al-Islami, a Kashmiri militant group associated with Al-Qaeda.". Is that enough to answer the question?
