A San Francisco firefighter said that 15 people were injured - including several children on their way to camp on Wednesday morning after two Muni buses crashed at Sixth at Market streets around 11 a.m.
Of the 15, only four injuries were considered moderate or serious, the firefighter said. None of the injuries were considered life-threatening.
Several of the passengers were children from the Vision Academy in the Bayview District headed to a take at the Cable Car museum.
Seven children were among those who were hurt in the crash, but none of their injuries were considered serious.
"It was a little chaotic initially," Fire Chief Joanne Hayes-White said.
The Muni F-train rear ended a F-Market and Wharves Muni bus at a slow rate of speed, according to Muni. Muni said one of the buses would have to be towed from the scene. The line was cleared and reopened by 1 p.m.
Harold Day, who said he witnessed the collision while walking across Market Street toward UN Plaza, told Bay City News the eastbound 9L was stopped and the streetcar was moving east slowing when it rear-ended the bus. He said he saw people on the bus get tossed around by the impact. He didn't see anyone with visible injuries, but he saw a girl crying and a man comforting her.
"It was really difficult to see that little girl ... crying," Day told BCN. "It was totally unreal."
Thais Schwab, a camp counselor with Vision Academy, said she was on the 9L with a group of 31 elementary and middle school students when the collision occurred. She said about 11 of them were injured when the bus was hit from behind.
