Pakistan will soon complete its investigation into the Pathankot terror attack and make it public, Prime Minister Nawaz Sharif said today, even as he acknowledged that the incident had a negative impact on Indo- Pak ties.

The attack disturbed the talks with India which were "going in the right direction" after the visit of Prime Minister Narendra Modi and External Affairs Minister Sushma Swaraj, he said.

"The investigation into the Pathankot incident is underway and we will make its findings public soon," he said while talking to reporters here.

"Whatever facts come out we will bring them forth before everyone," he said. Sharif vowed that Pakistan would go to any length to uncover the alleged use of its soil in the January 2 attack on the air base in Pathankot by suspected JeM terrorists.

"It is our responsibility to uncover if our soil was used in the attack. We will do this and the ongoing investigations will soon be completed," he said.

The terrorists were being defeated and in desperation, they were carrying out isolated acts to make their presence felt, he said, adding that the remaining ones will also be eliminated.

Meanwhile, Punjab Law Minister Rana Sanaullah said none of the 'suspects' arrested in connection with the attack have been charged.

"The investigation team is probing the matter and its findings will be made public," Sanaullah told reporters.

Responding to a question whether any link of Jaish-e- Mohammad (JeM) has been established with the attack, he said: "The investigation team is also probing this."

Sharif had formed a six-member committee headed by Additional Inspector General of Punjab's Counter Terrorism Department (CTD) to investigate the attack in which seven security personnel were killed.
