U.S. President Barack Obama on Monday challenged the Iranian leaders to take "immediate and meaningful steps" now to reduce tensions over its controversial nuclear program, one day prior to his departure for a visit to the Middle East.

Iran reopened talks last month with the so-called P5+1 group of the United States, Britain, China, France, Russia and Germany, and will have another round of talks in early April.
Obama will head for Israel, the West Bank and Jordan on Tuesday night for a three-day visit, his first trip abroad after starting his second term in January, with Iran's nuclear program, the Syrian conflict and the Israeli-Palestinian peace process expected to top his agenda.
In an interview with an Israeli TV on Thursday, the president said it would take "over a year or so" for Iran to make a nuclear bomb, and reaffirmed his administration's pursuit of a peaceful resolution.
