On August 1, 2008, CBS News reported that it had obtained a copy of an intercepted letter dated July 29, 2008, from unnamed sources in Pakistan, which urgently requested a doctor to treat al-Zawahiri. The letter indicated that al-Zawahiri was critically injured in a US missile strike at Azam Warsak village in South Waziristan on July 28 that also reportedly killed al Qaeda explosives expert Abu Khabab al-Masri. Taliban Mehsud spokesman Maulvi Umar told the Associated Press on August 2, 2008, that the report of al-Zawahiri's injury was false.
