NEW YORK - President Obama was heckled on Iran during his remarks at a campaign fundraiser here tonight when a supporter shouted, "Use your leadership! No war on Iran!"

"No one's announced a war, young lady," Obama said, drawing applause from the crowd of 900 mostly young professionals who crowded a showroom at ABC Carpet & Home for a $1,000 per person gala.

"You're jumping the gun a little bit there," Obama added.

The comments come amid growing tension between Iran and the West over its alleged nuclear weapons program and as Israel reportedly considers a pre-emptive military strike.

Obama is expected to discuss the Iranian situation with Israeli Prime Minister Benjamin Netanyahu at the White House early next week.
