Pakistan has turned down India’s proposal to jointly interrogate Jaish-e-Mohammed chief Maulana Masood Azhar and other suspects arrested in connection with the Pathankot attacks, The Nation reported. According to a senior government official, India wanted to send its investigators to interrogate Azhar and his brother, but Pakistan “politely refused” with assurances that it was investigating the case seriously and will not hesitate to bring those found guilty to justice.

Another official said investigators interrogating the arrested suspects were keeping India updated with any developments, adding that Pakistan had already sent them an initial report on the matter. Authorities held Azhar in protective custody after the incident and arrested several others suspected to be involved in the Pathankot attack, in which seven security personnel were killed. They also detained Azhar’s brother Mufti Abdul Rehman Rauf.

Moreover, Pakistani Prime Minister Nawaz Sharif said on Sunday that India had given his government “fresh leads” on the Pathankot attacks, PTI reported. “We are probing and verifying [the evidence]. Once we are done with that, we will definitely bring the facts forward. We have also formed a special investigating team; they will go to India and collect more evidence,” he said. Sharif’s statement follows United States President Barack Obama’s appeal to Pakistan to take more effective action against terror networks by “delegitimising, disrupting and dismantling” them.
