Patrick Calvar, head of the French General Directorate for Internal Security (DGSI) believes that Islamist extremists will look to increase their capacity to kill by using booby-trapped cars and bombs. Calvar made these remarks while testifying before a parliamentary commission examining French means to fight terrorism.
"We know very well that they will use these procedures; they have seen the effects of a massive operation. This happened in Belgium due to the fact that, having been caught, they could not engage in multiple attacks," Calvar was quoted as saying. "But once they have planted pyrotechnics in our country, they can avoid sacrificing their fighters while creating maximum damage."
