I want to know the answer to the following question:
Who were the rioters?
All the background I'm provided with is that "A mob of about 150 people armed with sticks, stones and metal rods attacked the police station in Mangishlak, about 90 miles from Zhanaozen, before they were dispersed by government troops flown in by helicopters.". Is that enough to answer the question?
Answer: no
