Brazil says it's dropping attempt to mediate Iran's nuclear dispute

Vienna: Brazil's foreign minister says his country's active support of Iran in its dispute with the West over its nuclear program is being scaled back after the UN Security Council decision to move for a fourth set of sanctions.

"We will help whenever we can, but of course there is a limit to where we can go," Celso Amorim told reporters on the sidelines of an official visit to Austria.

Brazil and Turkey last month brokered an Iranian nuclear fuel-swap deal in hopes that they would at least delay new UN sanctions, but the new penalties were imposed nonetheless.

Iran said Monday it has banned two UN nuclear inspectors from entering the country because they disclosed to the media the contents of a "false" report on the country's disputed nuclear program before the UN nuclear watchdog reviewed it.
