Obama visits firefighters and police in New York

US President Barack Obama arrived in New York City for an emotional visit to families and survivors of the September 11 terror attacks, hoping to mark an end to the decade long mourning and riding the waves of the death of Osama bin Laden just four days prior.

Obama will not make any public statements during his visit, but instead will meet with emergency responders, including a stop at a midtown Manhattan firehouse that lost 15 members in the attacks nearly 10 years ago.

He will also visit a police precinct in Tribeca .

Crowds outside the firehouse chanted U-S-A, U-S-A, as Obama arrived to have lunch with firefighters, joined by former Mayor Rudy Giuliani and Fire Commissioner Salvatore Cassano.

The President said that the 911 attacks were the high-water mark of courage for the New York fire-department, was that he was thankful for their services .

His visit marks the dramatic announcement that 911 mastermind, Osama Bin Laden, was killed at his Pakistan compound this previous Sunday.

Obama said on Monday at ceremony honoring military service members that the world is safer; it is a better place because of the death of Osama bin Laden.

Today, we are reminded that, as a nation, there's nothing we can't do -- when we put our shoulders to the wheel, when we work together, when we remember the sense of unity that defines us as Americans, Obama said.

The president will participate at the wreath laying ceremony at 1:25 p.m., meet with the families and responders, then depart shortly thereafter.
