Pakistan handed over its initial findings of the Pathankot terror attack probe to India on Tuesday, NDTV reported. 

Pakistan Prime Minister Nawaz Sharif had called for the formation of a joint investigation team (JIT) to probe the links of the Pathankot terrorists to Pakistan. 

The JIT comprised members of Pakistan's spy agency Inter-Services Intelligence (ISI), the Intelligence Bureau (IB) and the Military Intelligence (MI). 

On Monday, Pakistan carried out several raids and made five arrests in connection with the 2 January attack on the Pathankot airforce base based on leads provided by Indian authorities. 

The evidence provided by India is said to include voice recordings and phone numbers of the terrorists' handlers which were traced to Pakistan. 

However, Pakistan's Geo News has reported that the cell numbers given by India were not registered in Pakistan. 

The Pathankot attack is expected to derail talks between India and Pakistan scheduled this week, as India has insisted that Pakistan take immediate action on those involved.
