The Omar Khalid Khorasani's group, which is involved in attacking army school, wont be affected by the 10 airstrikes on N.waziristan. Omar Khalid is now operating independently from fazlullah in upper areas like Khyber, Mohmand etc with their base in Kunar. This man, khorasani, had differences with leadership over peace talks and had many differences with fazlullah , one of which was his insistence on attacking civilians.
This khorasani is the most hardcore one , once part of kashmir jihad, he is now Al-Qaeda-ish, not the type listening to the "akabareen" of deoband. Going against islamic teachings, he often talks of taking revenge. In this case he is saying that they have killed family members of army in school to "avenge" the murders of their family members by military.
