Pakistan's Prime Minister Nawaz Sharif called for a joint investigation team (JIT) to probe if the terrorists behind the Pathankot Air Force base attack had links to Pakistan.

The joint team will comprise members of Pakistan's spy agency Inter-Services Intelligence (ISI), the Intelligence Bureau (IB) and the Military Intelligence (MI), The Express Tribune reported. 

"PM Nawaz Sharif discussed the issue with army chief General Raheel Sharif and took him on board about the decision to form a JIT. This investigation will be a major test of the prime minister to move Pakistan-India relationship forward and to break the cycle of off-again on-again talks between the two neighbours," a source from the prime  minister's house told the news site.

The decision to form the team was reportedly taken during the high-level meetings that Sharif had held last week. 

The report comes amidst speculations over whether the 15 January foreign secretary-level talks would be held in Islamabad as per schedule or not. It was earlier reported that the talks had been called off, but Indian National Security Adviser Ajit Doval dismissed the reports.

However, Doval had told NDTV that India "will talk only if Pakistan takes action".

Indian Prime Minister Narendra Modi had urged Sharif to take "immediate action" in the investigation of the Pathankot attack, which, Indian intelligence officials have said, was perpetrated by the Pakistan-based Jaish-e-Mohammed terror group. 

US Secretary of State John Kerry had also brought up the Pathankot attack during his telephonic conversation with Sharif last week, and the latter assured that Pakistan "will soon bring out the truth", according to reports
