The authorities have closed the Peshawar Main Highway and suspended internet and mobile services in the area.

A provincial government delegation, comprising Khyber Pakhtunkhwa spokesperson Barrister Muhammad Ali Saif, Law Minister Aftab Alam, Chief Secretary Nadeem Aslam, IGP Akhtar Hayat Gandapur, Kohat commissioner, and other high-ups, met with the local chieftains.
The local leaders demanded the government ensure foolproof security for the main highway.
On Saturday, the relatives of the victims raised the demand for a transparent inquiry and stepped up efforts to maintain law and order in the region.
“A transparent inquiry of this incident should be carried out,” said Hayat Abbas Najafi, one of the mourners in Parachinar.
“We call on the government as well as security institutions that Parchinar, which is a great part of Pakistan, should be saved from sectarianism and should be provided safety and security.”
Sajjad Hussain, another mourner, said among those killed were infants as young as six months old and women.
“They were innocent passengers. What was their fault,” he asked.
No one immediately claimed responsibility for the attack, which came a week after authorities reopened a key highway in the region.
In July and September, similar skirmishes killed dozens of people.
