CAIRO – Al-Qaeda confirmed Tuesday that one of the group's most senior figures, veteran militant Abu Yahya Al-Libi, had died in a US drone strike earlier this year. The US government said in June it had killed Libi in Pakistan, dealing the biggest in a series of blows to the group since the raid that killed Osama Bin Laden last year. “I proudly announce to the Muslim umma and to the Mujahideen (holy fighters)... the news of the martyrdom of the lion of Libya Sheikh Hassan Mohammed Qaed,” Al-Qaeda leader Ayman Al-Zawahiri said in a video released on Islamist websites, referring to Libi by his birth name. Zawahiri's statement was the first acknowledgement by Al-Qaeda that Libi had died. Recently released letters written by Bin Laden and captured during the US raid in which he was killed show Libi was one of a handful of Al-Qaeda operatives who Bin Laden relied on to promote the group's case to a worldwide audience of militants, in particular to the young. A cleric, Libi escaped a high security US prison in Afghanistan in 2005. On at least one previous occasion was he was wrongly reported to have been killed in a US drone strike. The White House said in June it would be hard for the group to find someone of similar stature to replace him. Zawahiri's posting said the recording was made during the Muslim fasting month of Ramadan, which ran from mid-July to mid-August, but that it was released to coincide with the anniversary of the Sept. 11 attacks of 2001. He also mentions Warren Weinstein, an elderly US aid worker kidnapped in Pakistan by Al-Qaeda just over a year ago, vowing to keep him in captivity until US-led forces release Qaeda followers held in Afghanistan. – Agencies
