Daesh is currently instructing its "lone wolf" attackers on how to commit terrorist acts using poisons in shopping malls, Eitan Azani, the deputy director of the International Institute for Counter Terrorism, and Boaz Ganor, an expert on terrorism, said.
While the new tactic fits in the terror group's recent trend of carrying out "jihad on enemy land," according to Middle East expert Colonel Omar Locatelli, it is also not surprising that Daesh would try to diversify its attacks.
"Security measures on transport, for example, on airplanes, have become too tight, which is why today terrorists are looking for ways to carry out attacks in crowded places using vans," Locatelli told Sputnik, noting Daesh's most recent terror tool for killing as many people as possible.
Europe became a target for such attacks in July 2015 when a 19-tonne cargo truck rammed into a crowd in Nice, leaving 86 people dead. Since then, several similar attacks (in Berlin and Catalonia, for example) have spread fear all across Europe.
