"Global action to protect the nuclear industry against possible terrorist attacks is urgently needed, a leading expert said, as are safety steps to prevent any repeat of Japan's Fukushima accident.
"Both al Qaeda and Chechen terrorist groups have repeatedly considered sabotaging nuclear reactors -- and Fukushima provided a compelling example of the scale of terror such an attack might cause," Matthew Bunn of Harvard University said.
Some countries had "extraordinarily weak security measures in place," he said in an Internet blog posted this week, without naming them.
"The nuclear industry in many countries is much less prepared to cope with security incidents than with accidents," wrote Bunn, an associate professor at Harvard Kennedy School who specializes in nuclear issues."
