An intelligence officer and a senior government official said on Thursday that operations chief Ilyas Kashmiri was believed killed in an attack on September 7 in North Waziristan.
They said a strike on September 14 is suspected to have killed the Uzbek, named Nazimuddin, but who also was known as Yahyo.
They spoke on condition of anonymity because they were not authorised to speak to the media about the topic.
A US counterterrorism official said last week Kashmiri was in charge of al Qaeda's paramilitary operations in Pakistan.
Islamabad: Pakistani officials say al Qaeda's operations chief in Pakistan and an Uzbek operative are believed to have been killed in American missile strikes in the northwest of the country earlier this month.
