PESHAWAR: A 10th grade student of Peshawar's Army Public School (APS) succumbed to his injuries at the Combined Military Hospital on Saturday.

The student, Ishaq Ameen was shot in the head and face during the deadly attack on the Peshawar school on December 16, and had been in critical condition since, his brother Waqar said.

The death toll of the carnage now stands at 144, with 132 students among the dead, the Deputy Commissioner's office said.

The attack which was claimed by the Tehreek-i-Taliban Pakistan (TTP) proved to be the deadliest terrorist attack in the country.

After losing his son in the APS carnage, Mr Ali decided to create the forum comprising the grieving parents who he said wanted to take the situation in their control.

Speaking to Dawn, Mr Ali said the children and teachers would receive treatment at the orthopaedic and neurosurgery wards including plastic surgery needed for some students.

“Some students still have bullets in their bodies, some teachers still complain of feeling splinters in their back and hip bone, others need immediate neurosurgery as the required time to carry out such a surgery is running out,” he had said.

The Khyber Pakhtunkhwa government, he recalled, had announced on Feb 5 that the families of the injured would receive Rs1,500,000 for further treatment. “But we haven’t heard from them since then. At the same time, we don’t have time to wait for these promises to materialise, as some of these students need immediate help,” he added.

Shuhada-o-Ghazi Forum to lodge FIR against Nawaz Sharif, Pervez Khattak

The Shuhada-o-Ghazi forum announced on Saturday that a First Information Report (FIR) will be lodged against Prime Minister Nawaz Sharif and Khyber Pakhtunkhwa Chief Minister Pervez Khattak, over their negligence in treatment for injured APS students.

Shortly after the death of Ishaq Ameen, Shuhada forum spokesman Ajoon Khan told media representatives that the wounded were not being treated properly which is why they are succumbing to the injuries.

"Why is the government not making arrangements to take our injured children abroad for treatment?" questioned Khan.

The spokesman said that a legal board is being constituted for drafting an FIR against the premier and KP chief minister.
