IAEA members practice response to simulated dirty bomb VIENNA, Nov. 25 (UPI) -- IAEA Deputy Director Denis Flory said dozens of nations and international organizations tested their response to simulated dirty bomb attacks successfully. The International Atomic Energy Agency said 57 countries and nine international organizations took part in the so-called Bab al-Maghrib exercise, a simulated attack through bombs containing low levels of radioactive material. "This exercise provided an excellent opportunity to test information sharing with member states and our coordination with other international organizations," Flory said in a statement Monday. The simulated attack lasted 26 hours and started Nov. 21. The simulation was in a port city of Morocco, where health, national security and other first responders coordinated their actions to a series of mock explosions. Flory said member states were challenged by the need to collaborate closely while at the same time protecting sensitive national security interests, which the IAEA said was a "a challenging balance to achieve."
