I want to know the answer to the following question:
What did the attack between Rus and Byzantines lead to?
All the background I'm provided with is that "The Chronicle reports that Askold and Dir continued to Constantinople with a navy to attack the city in 863–66, catching the Byzantines by surprise and ravaging the surrounding area, though other accounts date the attack in 860.". Is that enough to answer the question?
Answer: no
