Iran's top nuclear negotiator said Tuesday the Islamic republic is ready for fresh talks with world powers over its atomic programme, and that is has updated its package of proposals.

"The Islamic republic's package of proposals is updated and ready and will be presented (to world powers)," Saeed Jalili, who also heads the country's Supreme National Security Council, told reporters.

"We hope a new round of talks will be held for reaching a world full of progress and justice ... insha' Allah (God willing)."

He said Iran was ready with a "revised" package which was updated, taking into consideration last year's global developments, which included the economic recession and the Georgian crisis.

Jalili said the package will be directed at the five permanent members of the U.N. Security Council - the U.K., China, France, Russia and the U.S., plus Germany.

The six world powers are to meet near Frankfurt Wednesday to look into harsher U.N. sanctions against Iran.

International pressure is mounting for a new round of tougher sanctions against Iran if it refuses to return to talks over its nuclear programme amid long-held suspicions it is working to develop atomic weapons.
