The Boeing 777 that crash-landed at San Francisco airport was "significantly below" its target speed near the runway and the pilot tried to abort the landing, US investigators say.

The pilot was flying into San Francisco for the first time at the controls of a 777, Asiana Airlines says.

The flight from Seoul with 307 people fell short of the runway on Saturday, killing two and injuring dozens.

The aircraft apparently hit a sea wall, ripping off its tail.

More than 300 people were on Asiana Airlines flight which had taken off from South Korea's capital, Seoul

Passengers and crew escaped down emergency slides as it burst into flames.

Asiana confirmed that two female Chinese teenagers died in the crash. They had been seated at the back of the aircraft.

They are believed to be the first-ever fatalities in a Boeing 777 crash.

San Francisco's coroner is currently trying to establish whether one of the two fatalities occurred after a passenger was run over by an emergency vehicle rushing to the scene of the crash.
