"There are reports of some ETIM terrorists also killed in the strikes," Pakistan military said in a new text message, state-run Xinhua news agency reported.
The Pakistan military had said over 50 "terrorists, mostly Uzbek" were killed in air strikes on their hideouts in North Waziristan, bordering Afghanistan.
The East Turkestan Islamic Movement (ETIM) is believed to have regrouped its fighters in the lawless Waziristan tribal region with the help of the Pakistani Taliban and other militant groups in the volatile region, the Xinhua report said making a rare reference about militants from Xinjiang taking shelter in Pakistan.
Xinjiang is witnessing a spate of militant attacks in recent times following unrest among the native Uyghur Muslims over the settlement of Hans from other parts of China.
The ETIM, an al-Qaeda backed outfit, has been accused of carrying out terrorist attacks in China.
The group is fighting for the independence of Xinjiang from China.
