Zaki-ur-Rehman's bail comes in the backdrop of Pakistan Prime Minister Nawaz Sharif vow on Wednesday to intensify the war on terror as mass funerals in the Peshawar attacks.

As Pakistan mourned its dead, Sharif said all political parties had decided to draft a national action plan against terrorists within a week and act upon it immediately.

"We announce that there will be no differentiation between 'good' and 'bad' Taliban and have resolved to continue the war against terrorism till the last terrorist is eliminated," the Pakistan Prime Minister said, following an all-party meeting.
