The militants, emboldened by their success in FATA, moved into Islamabad where they sought to impose an extremist Sharia government on Pakistan. Their base of operations was the Lal Masjid in Islamabad. After a 6-month standoff, fighting erupted again in July 2007 when the Pakistani Military decided to use force to end the Lal Masjid threat. Once the operation ended, the newly formed Pakistani Taliban, an umbrella group of all militants based out of FATA, vowed revenge and a wave of attacks and suicide bombings erupted all over North-West Pakistan and major Pakistani cities throughout 2007.
