Who is the number 2 leader in Al-Qaeda?

As of my last knowledge update in October 2021, the number two leader in Al-Qaeda was Ayman al-Zawahiri, who succeeded Osama bin Laden after his death in 2011. However, the status of leadership within terrorist organizations can change frequently due to various factors, including military actions or internal dynamics. For the most current information, it is advisable to consult recent news sources or intelligence reports.
