Summary: Last week, Indian authorities disrupted a terrorist plot to poison local water supplies, arresting three individuals with confirmed links to the Islamic State Khorasan Province, according to a report from Indago Solutions. This plot demonstrates the enduring appeal of foreign terrorist organizations (FTOs) targeting critical infrastructure services in furtherance of their ideological goals.
Analyst Note: In the past, malicious threat actors have attempted to use biological and chemical agents to target the water and wastewater sector. In 2018, for example, a Wisconsin based woman was charged with supporting the Islamic State by encouraging online supporters of the group she was in contact with to poison local water reservoirs with ricin. Before that, in 2015, Islamic State operatives plotted to poison water supplies in the European country of Kosovo, underscoring the persisting desire of FTOs to target public drinking water to conduct mass-casualty attacks.
In this latest plot, the accused terrorists reportedly planned to manufacture the highly toxic biological agent ricin and target water supplies, religious sites, and public areas in major Indian urban centers. The plot involved a multi-national operation directed by an external Islamic State Khorasan Province handler, who provided instructions and logistical support. Tactical gear, including firearms and ammunition, were smuggled over the border from Pakistan via drone. One of the alleged terrorists converted his residence into a makeshift laboratory, acquiring precursor chemicals, castor beans, and an oil-press machine to manufacture the ricin.
Indian authorities reported that the individual responsible for manufacturing the ricin had not yet successfully isolated the toxin or determined a delivery mechanism at the time of his arrest. “This was not a case of lone-actor radicalization but a directed cell with a mature command-and-control structure. The presence of an external handler, transnational weapons smuggling, and a clear division of labor indicate a sophisticated network,” according to the Indago Solutions report. Indeed, the Islamic State-Khorasan Province remains one of the most lethal Islamic State affiliate groups with a network of transnational contacts and a persistent desire to conduct external operations in Western countries.
