DUBAI  - Iran’s spy chief accused German and French intelligence agencies on Friday of involvement in assassinations of its nuclear scientists, sticking to a hard official line as sanctions imposed over its disputed atomic ambitions bite harder. The Islamic Republic has previously accused Israel, the United States and Britain of plotting the killings to set back its uranium enrichment program, which Western powers suspect is being used to develop nuclear weapons capability. Intelligence Minister Heydar Moslehi spread the blame to France and Germany, after days of hawkish rhetoric and missile tests by Tehran that helped push benchmark Brent crude oil prices above $100 for the first time since June.
