In December 1999 , Harkat terrorists hijacked the Indian Airlines Flight 814 scheduled to fly from Kathmandu to Delhi , and diverted it to Kandahar , where they were looked after by the Afghan Taliban and the Pakistani officials stationed at the airport . After they slit the throat of a passenger , the Indian government agreed to their demands and released Maulana Masood Azhar , Ahmed Omar Saeed Sheikh and Mushtaq Ahmed Zargar , three Harkat operatives previously imprisoned in India . The released prisoners were escorted to Pakistan by the ISI , and Masood Azhar was chosen to head the new group Jaish-e-Mohammed . The ISI is said to have paraded him on a victory tour through Pakistan to raise money for the new organisation . Some analysts argue that ISI built up the JeM to counter the growing power of Lashkar-e-Taiba ( LeT ) . Many analysts believed that around 1999 , Pakistan 's Inter-Services Intelligence ( ISI ) used JeM to fight in Kashmir and other places , and continues to provide it backing . Although the JeM has been officially banned in Pakistan since 2002 , it continues to openly operate several facilities in the country
