This is what happens when US chooses to interfere in Pakistan's affairs. Leave Pakistan alone & let it deal with its own affairs. If the US conducts more drone strikes over wider areas, you can expect to see more stuff like this happening. On the other hand, this TTP has shown virtually no distinction from the AQ, & I am sure they are infested in Pakistan's Bajaur & Mohmand agency; & they get their refuge in Kunar, Afghanistan. They said they wanted to avenge the death of OBL, I find that a bit strange, considering most Pakistanis didn't support him.
