New details of the final conversation between the Pakistan Taliban gunmen behind Tuesday's (16 December) Peshawar school massacre and their "commander" handler have now surfaced.

Following the gruesome massacre of 132 school children and nine staff members, a gunman by the name of Abuzar contacted his "commander" handler, Umar Adizai, who is reportedly identified as a senior Taliban militant of the Peshawar region.

"We have killed all the children in the auditorium. What do we do now?" Abuzar asked his handler Adizai, reported Dawn News.

"Wait for the army people, kill them before blowing yourself up," replied Adizai.

Following these exchanges, the two remaining suicide bombers reportedly attacked the special operation soldiers stationed outside the Army Public School's administration block.

These final intercepted conversations, as well as other shared messages through the entire seven and half hour siege on the Army Public School in Peshawar, were released by the Chief of Army Staff, General Raheel Sharif to officials in Afghanistan on Wednesday (17 December).

"Vital elements of intelligence were shared with the authorities concerned with regard to the Peshawar incident," read an official statement on the General Sharif's visit to Afghanistan.

The calls have been traced back to the Nazian district of Afghanistan's Nangrahar province and Pakistan authorities are now urging Afghanistan to take action.

Pakistan officials believe the Peshawar attack was conducted on order by the Pakistan Taliban leader Maulana Fazlullah who is believed to be hiding in Afghanistan's Nuristan province.

Meanwhile, a Pakistan court today (18 December) has bailed out the alleged mastermind of the 2008 Mumbai terrorist attacks, Zaki-ur-Rehman Lakhvi, that claimed 166 lives.

"Yes, the court has issued Lakhvi's bail orders today, against a surety amount of one million rupees ($10,000)," Defence lawyer Rizwan Abbasi told Reuters.
