LONDON, April 12 (Xinhua) -- Britain was seriously concerned about Iran's uranium enrichment activities, Foreign Secretary Jack Straw said in a statement on Wednesday.

    "The latest Iranian statement further undermines international confidence in the Iranian regime and is deeply unhelpful," the statement said.

    Straw urged Iran to suspend its atomic work immediately and return to talks.

    Iranian President Mahmoud Ahmadinejad announced on Tuesday that Iran had successfully enriched uranium, but stressing that it did not want to seek to develop nuclear weapons. Enditem
