Don't worry about. Years of counter insurgency and counter terrorism has hardened our resolve and has prepared our forces for anything. The TTP was a far greater threat and we expunged them.
However we must not relax. We must remain vigilant. The border must be fenced and our intelligence must continue their hard work but most of all we must retake lal masjid. Most likely one of their got a banner made. They cost 12 rupees sq feet so this banner would not have coated more than 130-150 rupees that's about a cost of one liter milk olper (110rs) and perk candy bar ( 10rs).
Most likely they did recon due to cameras and placed this banner at that location to hide from cameras. It was removed promptly.
These are simply scare tactics and this seems like the work of pumped up brats.
Their network was destroyed in Baluchistan and although TTP has morphed into ISIS, they are located in Afghanistan in nangahar.
And frankly let me tell you. People are done with the mujahideen, khilafat e.t.c stuff. They are done. Heck not even the Indian jihadis get support bcz the popular concept is that today they yell Pakistan zindabad but tomorrow they will attack us. Ten years of madness has drilled this in the nation.
