A bicyclist was fatally struck by a San Francisco Municipal Railway bus in the city's South of Market neighborhood this morning, a police spokesman said.
The bicyclist was hit by the Muni bus around 8:40 a.m. near Bryant and Division streets, San Francisco police spokesman Officer Albie Esparza said.
A fire official said the bicyclist was pronounced dead at the scene.
The medical examiner's office was responding to the area as of 9:15 a.m., Esparza said.
Bus service has been re-routed around the scene of the collision.
Muni's 27-Bryant and 47-Van Ness lines serve that area.
Nearby streets have also been shut down, Esparza said.
