Diplomats from the U.S., Russia and other world powers wrapped up a meeting with Iran today about its nuclear program. The deal they're trying to hammer out is this: Iran modifies its program so that it can't produce nuclear weapons. And in exchange, Western powers lift sanctions. Negotiators released a joint statement calling the talks substantive and useful. A senior U.S. official said it is going to take some hard work to reach an agreement. The talks will resume on April 7th.
