As President Obama and other NATO leaders wrap up a two-day summit today in Chicago, the ongoing dispute with Pakistan over reopening supply routes from that country into Afghanistan threatens to "put a crimp in the Obama administration's efforts to lay out a clear strategy for winding down the war in Afghanistan," NPR's Jackie Northam tells our Newscast desk.

It's been another deadly day in Yemen:

According to the BBC: "At least 63 people have been killed in a suicide bomb attack during a rehearsal for a military parade in the Yemeni capital, Sanaa, officials say. The assailant, who was reportedly wearing an army uniform, blew himself up among a group of soldiers at al-Sabin Square, near the presidential palace."

"That's got to be the prettiest thing I've ever seen," Brent Veltri of Salida, Colo., told The Associated Press, when asked about the eclipse of the sun that was visible across the western U.S. on Sunday afternoon and in much of Asia earlier today.

The celestial show attracted quite a crowd. According to the AP:

With National Dog Bite Prevention Week set to start Saturday, the Insurance Information Institute wants Americans to know that:

-- Insurers paid $479 million in home owner insurance claims involving dog bites last year, up 16.1 percent from the year before.

-- The number of such claims rose 3.3 percent, to 16,292.

-- The average cost per claim grew by 12.3 percent from the year before, to $29,296.

Update at 1:17 p.m. ET. Support Afghanistan In 'Different Way':

During their meeting in the White House, President Francois Hollande, the new socialist leader of France, said he told President Obama that he was committed to withdrawing French troops from Afghanistan by the end of the year.

But, the AP reports, Hollande said he was committed to supporting Afghanistan in a "different way."

This was Obama's first meeting with Hollande.

The two leaders also said they wanted Greece to remain a part the European monetary union.

Before President Obama welcomes world leaders to Camp David and Chicago, new French President Francoise Hollande is expected to say he wants his nation's 3,300 troops home from Afghanistan by year's end. That could upset other NATO nations.

Among the key things to know about what's in the hundreds of pages of evidence and other materials related to the Feb. 26 shooting death of Florida teenager Trayvon Martin, which were released Thursday:

Facebook's much-publicized first sale of stock to the public started with a bang late this morning as the price per share jumped. But though the volume of shares sold was a record for an initial public offering, the stock's price gave up its gains as the day continued.

By the end of trading in the U.S., Facebook had settled right at the $38 initial offering price that had been set before shares went on sale.

President Obama has said "I don't bluff," when it comes to opposing any effort by Iran to develop nuclear weapons (which that nation says it is not trying to do). And, he told The Atlantic's Jeffrey Goldberg in March, "all options are on the table."
