Iran has to answer nuclear case, says IAEA
The five permanent members of the UN Security Council, and Germany, have expressed their "increasing concern" over Iran's nuclear programme.
They have called for clarification over any possible military uses.
Tehran insists that the programme is for purely peaceful purposes.
The International Atomic Agency says they want to send a high level mission to Iran to clear up any confusion, as Bethany Bell reports from Vienna.
