Families of 9/11 victims hail killing of Ayman al-Zawahiri

Drone strike against al-Qaida leader praised across US political spectrum but 9/11 families press for Saudi accountability

Families torn apart by the deadly September 11 terrorist attacks celebrated Sunday's killing of Ayman al-Zawahiri, one of the top al-Qaida leaders behind the 2001 attacks, but they continued demanding accountability for the Saudi Arabian government's alleged role.

Meanwhile, Democratic politicians touted Zawahiri's death as a major accomplishment for Joe Biden.
