Lahore: A Pakistani team investigating the terror attack on the Indian Air Force base in Punjab's Pathankot town has asked Islamabad to seek more evidence from India, saying there had been "no headway" so far in the probe, a media report said on Monday.

"The team has almost completed its investigation into five cellphone numbers, allegedly used for making calls from Pakistan to India, provided by the Indian government. No further leads were found from these numbers because they were un-registered and had fake identities," Dawn quoted a source as saying.
