Crews knock down 2-alarm structure fire in SF's Nob Hill

San Francisco firefighters knocked down a building fire Thursday morning in the city's Nob Hill neighborhood.

The San Francisco Fire Department posted on social media shortly after 8:30 a.m. about the fire on Jackson Street near Leavenworth Street, saying they've encountered flames and smoke on all levels of what appears to be a three-story residential building.

No injuries were reported.

Riders on Muni cable cars through the area should expect delays in both directions, fire officials said.
