A Boeing 777 aircraft has crash-landed at San Francisco international airport, killing at least two people and injuring dozens more, officials say.
San Francisco Fire Chief Joanne Hayes-Whites said 48 people were initially taken to nearby hospitals.
She said 190 people walked to safety from the plane, some with minor injuries - 82 of whom were later transferred for medical treatment.
City Mayor Edwin Lee said: "This is still a fluid and active scene."
