Update 10:50 p.m.: And, here's a (very grainy) video of the skidding plane, thanks to NBC New York:
Update 9:00 p.m.: Here's Southwest's statement on the landing gear incident. The statement was posted to their site earlier on Monday, after which they promptly suffered some technical difficulties:
Southwest Airlines flight 345 landed at New York's LaGuardia at 5:40 PM Eastern Monday evening from Nashville. The aircraft is a Boeing 737-700. Eyewitness reports indicate the aircraft's nose gear collapsed upon landing. There were 150 people on board including Customers and Crew. All Customers have been deplaned and transferred to the terminal. Initial reports indicate local responders are caring for five Customers and three flight attendants who have reported injuries at this time. Southwest is cooperating with local authorities, and the NTSB has been notified.
The chronology of events here still isn't quite clear, but from reports emerging in the hours after the crash, there's a slightly more detail picture of what happened: it looks like the nose gear of the flight collapsed just after the plane landed safely on the ground.
As for operations at LaGuardia, at least some flights headed to the airport have started boarding passengers, after a delay.
Original Post: LaGuardia Airport in New York City stopped accepting flights on Monday evening after a Boeing 737 landed at the airport without its front landing gear. The Southwest flight 345, from Nashville, had previously reported possible issues with its landing gear.

There are no reports of serious injuries or fatalities. Every passenger made it off the flight OK, according to multiple reports.

LaGuardia, meanwhile, is not closed, despite earlier reports. But it's not accepting incoming flights. Initial reports indicate that the front landing gear collapsed after landing.
