Islamabad, Jan 9 (IANS): Pakistan needs concrete evidence from India for acting against the elements involved in the terror attack at the Pathankot air base in Punjab, a media report said on Saturday.

"We are expecting evidence beyond leads and information to proceed as per our law," Dawn online quoted a senior official as saying.

Pakistani Prime Minister Nawaz Sharif on Thursday chaired a meeting of security aides on the Pathankot attack and Pakistan's response on it.

The official's comments provided an insight into Pakistan's planned response to India on the shared leads about the attack.

The information include intercepts of telephone calls made by the militants to their handlers, and the locations of the numbers which they had called in Pakistan.

Sharif, who had telephoned his Indian counterpart Narendra Modi, assured him of "prompt and decisive action" against those found guilty.

Militant organisation Jaish-e-Muhammad was behind the attack, Indian officials said.

Modi, during his telephonic conversation with Sharif, stressed the need for Pakistan to take firm and immediate action against "the organisation and individuals" responsible for the attack.

According to reports, the meeting reviewed the "progress on the information shared by India" and decided to continue discussing the matter with Indian authorities.
