VIENNA, Austria - Western diplomats and nuclear experts voiced growing concern Tuesday that Iran has reneged on its promise to fully suspend uranium enrichment - a process that can be used to make nuclear weapons.
Now, diplomats told The Associated Press on condition of anonymity, even key European nations who negotiated the deal with Tehran have started to question Iran's commitment because it appears to be using semantics - the meaning of the word suspend - to keep some of its nuclear enrichment program operational.
