The State Department"s annual survey of global terrorism released on Wednesday said Iran and its proxies are responsible for fomenting violence in Afghanistan, Bahrain, Iraq, Lebanon and Yemen. The report said Iranian fighters and Iran-backed militias, like Lebanon"s Hezbollah, had emerged emboldened from the war in Syria and with valuable battlefield experience they seek to leverage elsewhere. "Iran remains the world"s leading state sponsor of terrorism and is responsible for intensifying multiple conflicts and undermining US interests in Syria, Yemen, Iraq, Bahrain, Afghanistan, and Lebanon," he said. All three -- Daesh, Al-Qaeda and Iran -- "have both the capability and intent to strike the United States and our allies," State Department Coordinator for Counterterrorism Nathan Sales said. The report indicated a general increase in global cooperation to fight terrorism, including tracking and blocking financial flows to the groups. But this remains a challenge, Sales noted. "You have got to stop the flow of money to these organizations." "You have got to stop terrorist travel" as well, he added, pointing to the spread of airport detection systems like biometric face identification as a potent tool. In addition, the survey reported a 24 percent decrease in attacks around the world between 2016 and 2017. That was due mainly to a sharp decline in the number of attacks in Iraq, where the Daesh group has been largely displaced.
