Hasan Sarbakhshian/APANKARA (Reuters) - Iran's elite Islamic Revolutionary Guards said on Thursday that the country's ballistic missile program would accelerate despite pressure from the United States and European Union to suspend it, the semi-official Tasnim news agency reported. In a major U.S. policy shift, President Donald Trump last Friday refused to certify Tehran's compliance with a landmark 2015 nuclear deal, signaling he would take a more aggressive approach to Iran over its ballistic missile program. "Iran's ballistic missile program will expand and it will continue with more speed in reaction to Trump's hostile approach towards this revolutionary organization (the Guards)," the Guards said in a statement published by Tasnim. The Trump administration has imposed new unilateral sanctions targeting Iran’s missile activity.
