I want to know the answer to the following question:
How did the attackers kill themselves?
All the background I'm provided with is that "Ten months later, 13 November 2015, came a series of coordinated terrorist attacks in Paris and Saint-Denis claimed by the 'Islamic state' organisation ISIL ('Daesh', ISIS); 130 people were killed by gunfire and bombs, and more than 350 were injured.". Is that enough to answer the question?
Answer: no
