Haider Khalol was Chief of the Inter-Services Intelligence (ISI) intelligence agency of Pakistan during the 2010s. In 2015, he led the ISI's investigation of former Indian Army soldier Daniyal Khan after he called the Pakistani High Commissioner in London, Shahriyar Beg, and claimed to have evidence that Lashkar-e-Taiba leader Sajid Majid's death was not an accident, but an RAW assassination. Khalol, unlike his subordinate Firoz Bhatt, trusted Khan and arranged for him to meet LeT representatives in Syria, where the ISI could verify Khan's claims and judge whether he could meet the LeT leaders Haaris Saeed and Sahabuddin Umavi in Pakistan. In Syria, the ISI had Khan betrayed, kidnapped, and interrogated, and LeT commander Mukul Qureshi attempted to videotape a confession by Khan. However, the signal connection was too poor for Qureshi to send the video to the ISI, and he was killed by Khan just after reaching a better zone; the ISI heard Qureshi mention Khan's name before Qureshi was shot. From then on, Khalol directed the ISI to track down Khan, and he also ordered the assassination of Indian diplomat Rajan Sampat in Amman, Jordan in retaliation for Qureshi's death. At the same time, Khalol realized that Khan was the same man who had attempted to assassinate David Headley in a Chicago prison under the alias "Jude Rosario", and he realized that Khan intended to assassinate the LeT leadership. The ISI was too late to prevent Khan and his accomplice Nawaz Mistry from eliminating Saeed and Umavi in concurrent assassinations in Lahore and Rawalpindi, but, by then, the ISI had tracked Khan down to Lahore, and they managed to cut off Khan and Mistry's maritime escape route from Karachi after tracking down their car's license plate number. Khan was killed by the Pakistan Navy before he could rendezvous with the Indian Navy in international waters, but Mistry was able to escape.
