Asiana Airlines flight crashes while landing at San Francisco airport, Fox News confirms.
It was not immediately known whether there were any injuries.
Federal Aviation Administration spokeswoman Laura Brown says the plane was coming from South Korea and was supposed to land on runway 28 left at San Francisco International Airport.
She said the sequence of events was still unclear, but it appeared the plane landed and then crashed.
A video clip posted to Youtube shows smoke coming from the silver-colored Boeing 777 jet on the tarmac. Passengers could be seen jumping down the inflatable emergency slides.
The plane was traveling from South Korea. It was not immediately known how many passengers the plane was carrying. A Boeing 777 can carry between 246 to 300 passengers.
The airline, founded in 1988, is based in Seoul, South Korea.
