Pakistani jets and ground forces killed 67 militants in a northwestern tribal region near the Afghan border, officials said, days after the Taliban killed 148 people - mostly children - in a school massacre.
The mass attack on children has stunned the country and brought cries for retribution.
In the past few days the military have struck a number of targets in the Khyber region, and approved the death penalty for six convicted terrorists.
Khyber borders Peshawar, where the massacre took place, and militants traditionally attacked the city before fleeing into the tribal area where they cannot be chased.
The government is appearing to demonstrate its commitment to fighting terrorism, but this was somewhat undermined by the decision to grant bail to the main suspect in the Mumbai terror attacks, Zaki-ur-Rahman Lakhvi. The government said it is trying to cancel the bail.
A number of protests and ceremonies for have been taking place across India in memory of the victims of a Taliban gun attack on school in Peshawar, Pakistan.
The attack on an army-run school in Peshawar was so severe it "shocked" everyone, not just those with relatives in Pakistan, a Bradford councillor has told Good Morning Britain.
Khadim Hussain said Brits "irrespective of what colour or creed they are" would be sickened by the Taliban attack, which killed 141 people, most of them children.
More is now known about the Pakistani Taliban group who carried out the massacre in Peshawar and the man who ordered it.
Maulana Fazlullah also ordered the school attack in which Malala Yousefzai, almost lost her life.
