With al-Zawahiri's death, all of top plotters of the Sept. 11 terrorist attacks are either dead or captured.Zawahiri continued to release video statements, including one on Sept. 11, 2021, although it was unclear if that recording was new or old. It was rumored for years that he had died, and the U.S. offered $25 million for information that could lead to his apprehension. — CBS News' Arden Farhi, Nancy Cordes, Andres Triay, Ahmad Muktar, Pat Milton and Olivia Gazis contributed to this report.   5:21 PM How to watch Biden's remarks What: President Biden addresses a "successful" counterterrorism operation in AfghanistanDate: August 1, 2022Time: 7:30 p.m. ETLocation: White HouseOnline stream: Live on CBS News streaming in the player above and on your mobile or streaming device.
