I want to know the answer to the following question:
What chained actions resulted from the alleged violation of the Constitution of Medina by the Banu Qaynuqa Jews?
All the background I'm provided with is that "This escalated to a chain of revenge killings, and enmity grew between Muslims and the Banu Qaynuqa, leading to the siege of their fortress.:122". Is that enough to answer the question?
Answer: yes
