Pakistan's intelligence agency, the ISI, is reportedly using individuals under the influence of drugs or posing as mentally disturbed to infiltrate India and deliver messages to terrorists in prisons. Officials have reported over 10 such cases since July, with individuals entering from Pakistan and Pakistan-occupied Kashmir and being sent to prisons in Jammu, Punjab, and Rajasthan. Security agencies suspect these individuals are couriers tasked with relaying communication to jailed terrorists. The ISI's tactic is believed to be a response to the increased use of technology in communication, which leaves behind electronic footprints. This method of infiltration has also been linked to drug smuggling operations. The ISI's current tactic is reminiscent of its past use of "sawari operators" on the Samjhauta Express for covert operations, which were effectively curtailed by authorities.
