The offensive comes after a Taliban suicide bomber killed 73 people in a popular Lahore park. Jamaat-ul-Ahrar, the Taliban faction that carried out the bombing, said Christians were the target of the attack.
The incident illuminated festering extremism in Punjab, the home province of three-time Prime Minister Nawaz Sharif and provincial authorities said they would launch a crackdown against militant groups in the province.
The country is still scarred by a Taliban assault on a Peshawar school in 2014 that killed 150 people, mostly children.
A military operation targeting insurgents was stepped up in response. Last year the death toll from militant attacks was the lowest since the Pakistani Taliban was formed in 2007.
