WASHINGTON (Reuters) - The world is losing patience with Iran's behavior over its nuclear program and Tehran will be responsible for the consequences if it fails to meet its obligations, the White House said on Friday.

Robert Gibbs, President Barack Obama's chief spokesman, said a vote by the U.N. nuclear watchdog to rebuke Iran illustrated the "resolve and unity" of the international community over Iran's nuclear program.

The International Atomic Energy Agency's board of governors voted 25-3 to censure Iran in a decision that gained rare backing from Russia and China, which have in the past blocked attempts to isolate Iran, a trade partner for both.

"Our patience and that of the international community is limited, and time is running out," Gibbs said in a statement. "If Iran refuses to meet its obligations, then it will be responsible for its own growing isolation and the consequences."

One U.S. official, speaking on the condition of anonymity, stressed that a "package of consequences" would result if Iran did not prove to be a serious partner in talks with world powers about its nuclear program.

"We hope that the board of governors resolution reinforces the message that, you know, we're committed to putting together a package of consequences if we don't find a willing partner," the official told reporters. "We hope Iran takes note of that clear message."
