The killings of some 16 civilians in Afghanistan on Sunday allegedly by a U.S. soldier are raising new questions about U.S. military strategy: whether the surge of American troops worked, and whether the U.S. troops have won over the Afghan people or alienated them.

The place where the killings happened was a "no-go zone" for American and even Afghan troops as recently as two years ago — it was Taliban country.

The vaccine — $417,000 worth of it — is stacked high in refrigerated containers to protect it from the Haitian heat.

Hundreds of health workers are trained and ready to give the vaccine. They're armed with programmed smartphones and tablet computers to keep track of who has been vaccinated and who needs a second dose.

And 100,000 eager Haitians, from the teeming slums of Port-au-Prince to tiny hamlets in Haiti's rice bowl, have signed up to get the vaccine.

For many following the Republican presidential contest, the big question is who's winning.

That's not easily answered if you go only by who has won each state's primary or caucus. But if you measure who's won the most pledged convention delegates, former Massachusetts Gov. Mitt Romney is clearly in the lead.

So much so, in fact, that Romney's campaign insists there's no way his rivals can catch up or keep him from getting the 1,144 delegates needed for securing the nomination in Tampa this summer during the Republican National Convention.

The American journalist killed while on assignment in Syria was laid to rest in New York today.

At a ceremony in Oyster Bay, New York, Marie Colvin, who worked for the British paper The Sunday Times, was remembered as an "outstanding reporter" who took risks because she thought what she did was important.

So Mitt Romney is turning 65. And on his landmark birthday, he's doing the exact opposite of what roughly 99 percent of Americans do at that age: He's not signing up for Medicare.

The news was broken by the blog Buzzfeed, and quickly confirmed by the Romney campaign.
