Three days after the Uri terror attack, India Today has learned from sources that Jaish-e-Mohammad’s (JeM) Kashif Jaan, Rauf Asgar and Masood Azhar may have masterminded the brazen attack.Kashif Jaan, the JeM operative who had escorted the Pathankot terrorists till the border, could also have been the handler of the terrorists who carried out the attack in Uri, sources in the National Investigation Agency (NIA) told India Today. The NIA suspects that the JeM handler could have gone underground post the Uri attack. After a preliminary investigation confirms the role of the three JeM men, India will ask Pakistan to arrest these terrorists and hand them over to India. Not ready to let Pakistan slip away, India, this time, will seek the support of international agencies to force Pakistan to act against these homegrown terrorists. NIA COLLECTS EVIDENCE In another development, the Army has handed over crucial evidences and documents related to the Uri terror attack to the NIA. A team of NIA officials is also collecting evidences and samples from the attack site in Uri to zero down on the perpetrators who carried out one of the most dastardly attacks on the Indian army.ALSO READ: Uri attack: Parrikar seeks report from Army on how terrorists managed to infiltrate camp Sources said that the NIA is working on different theories and will take the help of the Intelligence Bureau (IB) and the Research and Analysis Wing (RAW) to collect incriminating evidence. DNA SAMPLES WILL BE THE KEY The NIA will also collect DNA samples of the slain terrorists. It will seek the help of the Army, IB and RAW to get the identities of the terrorists verified. Sources have told India Today that once the identities are verified, the NIA will identify the relatives of the terrorists in Pakistan and confront its neighbour and ask for the samples of the relatives. Sources in the Ministry of Home Affairs (MHA) said that in the Pathankot terror attack case, despite repeated reminders, Pakistan did not provide the DNA samples of the Pakistan-based relatives of the slain terrorists. The MHA will discuss the matter with the Ministry of External Affairs and try to take it up with Pakistan. The MHA does not want a repeat of the Pathankot case and is keen to not allow Pakistan to sleep over the DNA sample issue in the Uri attack case.advertisementALSO READ: Uri attack: India to respond at multiple levels, but will the stand be aggressive?
