Thanks to a "lurker" for the pointer to this apparent ISI press briefing:
Local intelligence officials said foreign militants along with their families have taken refuge there in recent years, including Chechens, Uzbeks, Chinese, Turkmen, Tajiks and Uighurs.

One senior security official said the military was in particular targeting the East Turkestan Islamic Movement, a separatist militant outfit blamed for numerous terror attacks in China’s restive western region of Xinjiang.


He said the Chinese government had pressed Pakistan for taking action against the Uighur separatists based in North Waziristan. “The Chinese authorities had conveyed their message separately to the prime minister and the army chief; the issue had been raised even with the president when he was on an official visit to China,” he added.


The military action comes after more than three months of stop-start peace talks between the government and the outlawed Tehreek-i-Taliban Pakistan, which have made little progress since they began in February.
