HARI SREENIVASAN: The Syrian military escalated attacks on rebel areas today, despite the government's claim that it is adhering to a cease-fire.
In the central city of Homs, amateur video showed large plumes of smoke rising. Mortar rounds and shells rained down on rebel-held sections. Elsewhere, two vehicles carrying U.N. observers were surrounded by thousands of anti-government protesters near Damascus. Then, gunfire erupted as Syrian security agents fired on the crowd, and the observers were forced to flee.
In Brussels, Belgium, U.S. Secretary of State Hillary Clinton condemned the violence.
SECRETARY OF STATE HILLARY CLINTON: It is obviously quite concerning that while we are deploying these monitors pursuant to a Security Council resolution that confirms our commitment to Kofi Annan's six-point plan, the guns of the Assad regime are once again firing in Homs, Idlib and elsewhere, and Syrians continue to die.
HARI SREENIVASAN: Clinton said Syria has reached a turning point, and she warned of new pressure on the government, unless it relents.
At least 22 soldiers died today in growing border fighting in East Africa between Sudan and South Sudan. There have been almost daily battles since South Sudan seized the oil town of Heglig last week. Sudan today demanded an immediate withdrawal. South Sudan claimed its independence last summer, but the border was never settled, and the two sides never agreed on sharing the region's oil wealth.
In the U.S. presidential campaign, President Obama and Mitt Romney traded criticisms over economic policy. The president traveled to the swing state of Ohio, and he charged that Republicans are dead wrong on how to build a recovery.
He spoke to a community college in Elyria near Cleveland.
PRESIDENT BARACK OBAMA: In this country, prosperity does not trickle down. Prosperity grows from the bottom up, and it grows from a strong middle class out.
(CHEERING AND APPLAUSE)
BARACK OBAMA: That's how we grow this economy.
And that's why I'm always confused when we keep having the same argument with folks who don't seem to remember how America was built.
HARI SREENIVASAN: Mitt Romney offered the Republican answer this afternoon in Charlotte, N.C.. He accused the president of pitting Americans against each other to divert attention from his own failed policies.
MITT ROMNEY (R): One of the things that is most disappointing to me in our president has been that, over the last 3.5 years, he has engaged in constant efforts to divide Americans and to find blame of one after another.
MITT ROMNEY: And each day, if there's a problem of some kind, he points to some group of Americans that must be responsible for it, never saying he's responsible for the mistakes he's made, for policies that made it harder for businesses to start and for people coming out of school to find a good job.
HARI SREENIVASAN: Romney also said today he would clean house at the Secret Service. He called for firing 11 agents who allegedly used prostitutes in Colombia ahead of a presidential visit last week. This evening, the Secret Service announced three of the agents are leaving its employ. It says the investigation will continue.
Wall Street gave back some of its gains of the last few days. The Dow Jones industrial average lost more than 82 points to close at 13,032. The Nasdaq fell 11 points to close at 3,031.
A retired couple in southern Illinois has claimed the final share of last month's record Mega Millions lottery jackpot. Merle and Patricia Butler came forward today and took home a lump sum of $111 million, after taxes. Butler said even when he matched the winning numbers to his $3 ticket, it took a few moments for the realization to sink in.
MERLE BUTLER, Mega Millions winner: After I looked at it for a couple minutes, I turn to my wife, who was right there with me, and I says, "We won." And she kind of looked at me funny.
MERLE BUTLER: And I says, "No, we won."
And then she started giggling.
MERLE BUTLER: And she giggled for about four hours, I think, you know?
HARI SREENIVASAN: The overall jackpot totaled $656 million. The other winners in Kansas and Maryland have chosen to remain anonymous.
