U.S., EU vow tougher sanctions over Iran nukes

'Additional measures'
"A mutually satisfactory, negotiated solution remains open to Iran," the statement said. But the leaders also said that they would fully implement U.N. sanctions against Iran and were "ready to supplement those sanctions with additional measures."

Bush warned that if Iran ends up with a nuclear weapon, "the free world is going to say why didn't we do something about it at the time? ... Now's the time for there to be strong diplomacy."

Iran's central bank, also known as Bank Markazi, is involved in these deceptive acts, according to the U.S. government. The White House has been looking at new steps to cut off more Iranian banks from the international financial system and has been seeking backing from European allies.

Tensions over Iran are only rising. An Israeli Cabinet minister warned Friday that Israel will attack Iran if it doesn't abandon its nuclear program. Israeli Prime Minister Ehud Olmert distanced himself on Sunday from the statements but didn't explicitly reject them.

Verbal threats and political tensions have increased between Iran and Israel after Iran's hard-line President Mahmoud Ahmadinejad said in 2005 that Israel should be "wiped off the map."

"First of all if, if you were living in Israel you'd be a little nervous, too," Bush said. "If a leader in your neighborhood announced that they, he'd like to destroy you. And one sure way of achieving that means it through the development of a nuclear weapon. Therefore, now is the time for all of us to work together to stop them."

Bush said that Saudi Arabia's call for a summit between oil producing countries and consumer states to discuss soaring energy prices was "an interesting idea."

The leaders also called for the United Nations to send a team to Zimbabwe to monitor the human rights situation ahead of the second round of presidential elections on June 27. And they urged all sides to refrain from further violence over Tibet.

Bush was to fly to Berlin later Tuesday for a social dinner with German Chancellor Angela Merkel. During his weeklong stay in Europe, he also is going to Italy, France, London and Belfast.
