The three heavily-armed terrorists killed while attempting to attack the RSS headquarters in Nagpur, have been identified as Pakistanis, CID sources said Friday.

"They were identified as Afzal Ahmad Butt and Abu al Kalam Alad, both from Lahore [Images] while the third ultra was Mohammad Usman Habib from Gujranwala in Pakistan," a top official of state CID told PTI.

"Their identity could be established on the basis of seized diaries" where names were written in Urdu along with their telephone numbers, he said adding their links with Islamic militant organisations was, however, yet to be ascertained.

Nagpur Police Commissioner S P S Yadav told PTI, "We have no information (regarding their identities) since we have not received possession of dead bodies and materials (diaries) seized from them".

Regarding ownership of the white Ambassador car used by the terrorists and the identity of the 5.6 kg of explosives recovered from the vehicle, Yadav said "We are expecting definite information by later today".
