President George W. Bush prodded Russian President Vladimir Putin on Monday to press Iran, through the United Nations, to suspend verifiably its nuclear enrichment work.
The call came about a week after Putin visited Tehran, marking the first visit by a Kremlin leader to the Iranian capital in World War II.
A senior US official said Putin told Bush he continues to share US misgivings about Iran's nuclear ambitions and said nothing to indicate that the Kremlin had changed its concern about the prospects of a nuclear-armed Iran.
On a trip to Iran last week for a summit of Caspian Sea nations, Putin warned against any military attack on Iran. "We are saying that no (Caspian) nations should offer their territory to outside powers for aggression or any military action against any of the Caspian states," Putin said.
