VIENNA (Reuters) - The U.N. nuclear watchdog chief is "positively considering" a U.S. Senate invitation to speak about his agency's monitoring role in Iran following the country's deal with world powers on curbing its atomic activity, a diplomatic source said.

Some members of the U.S. Congress, which will consider whether to approve the deal, have asked for more information to be made public relating to the International Atomic Energy Agency's part in verifying Iran's implementation of the pact.
