Khan has faced criticism for initiating talks with the TTP group, which agreed to a cease-fire until Dec. 9. The TTP and Pakistan say Afghanistanâs Taliban government facilitated the agreement hoping to ensure peace in Pakistan.
However, the truce comes ahead of the seventh anniversary of the school attack that was claimed by the TTP. The attack left 147 people dead, including 132 schoolchildren.
The truce has angered many Pakistanis opposed to any peace talks with militants.
Judges on Wednesday asked Khan whether âwe are bringing them (the TTP) back to the negotiating table instead of taking action against them,â according to Pakistanâs DAWN newspaper.
It said the judges continued to fire questions and allegations at Khan, saying: âYou are in power. The government is also yours. What did you do? You brought those guilty to the negotiating table.â The court was referring to TTPâs culpability for the school attack.
Khan promised to take action against those accused of negligence in preventing the attack following a new investigation.
Authorities have said they arrested all those who masterminded the attack or took part in the 2014 assault. Five militants were hanged after being sentenced to death by a military court.
Parents of the slain schoolchildren want action against those army officials whose negligence led to the attack.
The next court hearing will be held after four weeks.
