ABC News learned late tonight that Shaikh Sa'id al-Masri, also known as Mustafa Abu al-Yazid and the man considered al Qaeda's third in command, has been killed. U.S. officials say that al Qaeda released a eulogy about the death of the Egyptian-born al-Masri, pictured above and known as the chief operating officer for the terror organization. He was trumped in rank only by Osama Bin Laden and Ayman al Zawahiri. It is believed that al-Masri was killed about a week ago in Pakistan. And while it remains unclear exactly how, it very likely involved one of the many drone strikes being used by the U.S. military in the region. So tonight, we ask: Is this further evidence that we should increase the use of drones in the war on al Qaeda's leadership? Even at the cost of significant collateral damage? Tell us what you think.
