I want to know the answer to the following question:
What opposition movement was based in Arabia and Basra?
All the background I'm provided with is that "Following the death of Husayn, Ibn al-Zubayr, although remaining in Mecca, was associated with two opposition movements, one centered in Medina and the other around Kharijites in Basra and Arabia.". Is that enough to answer the question?
Answer: yes
