And we're also reporting on violence on the border between Israel and the Gaza Strip. The attacks stretched the weekend into today. Israeli airstrikes killed three more people today in Gaza - that Palestinian-held area - bringing the total to 21.
As Israelis have been bombing, Palestinians have been firing rockets into Israel. And NPR's Lourdes Garcia-Navarro is following this story.
In recent weeks and days, the divisions over how to deal with Iran and its nuclear program have sharpened. The only undisputed fact is that Iran is developing a nuclear energy program, but after that things get murky.
Israel and some European countries believe Iran is moving toward a nuclear weapons program, but U.S. intelligence agencies disagree. Israel argues that a nuclear-armed Iran poses an existential threat, and there's much speculation in the media about a possible Israeli attack on Iran's nuclear sites.
Republican presidential candidates this week — with the exception of Ron Paul — appeared to be trying to outdo each other in saying how tough they would be in dealing with Iran. Speaking before a pro-Israel group, they said President Obama has been weak — "feckless," in Mitt Romney's words.
Obama, meanwhile, was not impressed. He said he'd heard a lot of "bluster" and "big talk" about Iran, "but when you actually ask them specifically what they would do, it turns out they repeat the things that we've been doing over the last three years."
